Answer:
short_names = ['Gus', 'Bob','Zoe']
Explanation:
A list is a type of data structure in python that allows us to store variables of different types. Each item in a list has an index value which must be a integer value, and the items can be assessed by stating the index position. The syntax for creating and initializing a list is:
list_name = [item1, item2,item3]
The name of the list (must follow variable naming rules)a pair of square bracketsitems in the list separated by commas.The python code below shows the implementation of the solution of the problem in the question:
short_names = ['Gus', 'Bob','Zoe']
print(short_names[0])
print(short_names[1])
print(short_names[2])
The output is:
Gus
Bob
Zoe
To initialize the `short_names` list with 'Gus', 'Bob', and 'Zoe', assign these names to the list variable and use the `print()` function to print each name individually. This is how the program achieves the required output.
To initialize a list in Python with specific strings, you can simply assign the list elements directly to a variable. Here is how you do it:
short_names = ['Gus', 'Bob', 'Zoe']
Next, to print each element individually as specified in your program, you can use the print() function:
print(short_names[0])print(short_names[1])print(short_names[2])When you run this code, you will get the following output:
Gus
Bob
Zoe
Here is the complete code for clarity:
short_names = ['Gus', 'Bob', 'Zoe']Print a message telling a user to press the letterToQuit key numPresses times to quit. End with newline. Ex: If letterToQuit = 'q' and numPresses = 2, print: Press the q key 2 times to quit.
Answer:
public class Assignment {
public static void main (String [] args) {
char letterToQuit;
int numPresses;
letterToQuit = '?';
numPresses = 2;
System.out.println("Press the " + letterToQuit +
" key " + numPresses + " times to quit.");
}
}
Explanation:
Using the Java Programming Language we implement a simple solution. Firstly you declare and assign values to the two variables needed for the program.
letterToQuit of type char and numPresses of type int We assigned the values '?' and 2 respectively to the variables, then using string concatenation the output Press the ? key 2 times to quit. is displayed with the System.out.println function
To print a message instructing the user to press a specific key a certain number of times to quit, use Python's print function with string formatting. For example, if letterToQuit is 'q' and numPresses is 2, the code will print: Press the q key 2 times to quit.
Printing a Custom Message in Python
To print a message that tells a user to press a specific key a certain number of times to quit, you can use Python's print function. Here is how you can do it step-by-step:
Store the key to quit in a variable, letterToQuit.Store the number of presses required in another variable, numPresses.Use Python's string formatting to create the desired message.Print the message using the print() function.Here's an example Python code:
letterToQuit = 'q'In this example, if letterToQuit is 'q' and numPresses is 2, the output will be:
Press the q key 2 times to quit.
This simple code illustrates the basic usage of string formatting and the print function in Python, making it easy to provide clear instructions to a user.

Explanation:
The answer to the question asked are C which implies that Objective.AccessLevel="All" and D which implies that the Objectivename.AccessLevel="None"
It is good to also know and understand that the narrative in the question and answer to the question are terms used in the Apex sharing sales force.
A share object includes records supporting all three types of sharing: managed sharing, user managed sharing, and Apex managed sharing. Sharing granted to users implicitly through organization-wide defaults, the role hierarchy, and permissions such as the “View All” and “Modify All” permissions for the given object, “View All Data,” and “Modify All Data” are not tracked with this object.
It should also be understood that :
The level of access that the specified user or group has been granted for a share sObject. The name of the property is AccessLevel appended to the object name. For example, the property name for OperateShare object is OperateShareAccessLevel. where valid values are usually,Edit , Read , All
Your program Assignment Write a program that reads a sentence as input and converts each word to "Pig Latin". In one version of Pig Latin, you convert a word by removing the first letter, placing that letter at the end of the word, and then appending "ay" to the word. Here is an Example: English: I SLEPT MOST OF THE NIGHT Pig Latin: IAY LEPTSAY OSTMAY FOAY HETAY IGHTNAY
Answer:
theSentence = input('Enter sentence: ')
theSentence = theSentence.split()
sentence_split_list =[]
for word in theSentence:
sentence_split_list.append(word[1:]+word[0]+'ay')
sentence_split_list = ' '.join(sentence_split_list)
print(sentence_split_list)
Explanation:
Using the input function in python Programming language, the user is prompted to enter a sentence. The sentence is splited and and a new list is created with this statements;
theSentence = theSentence.split()
sentence_split_list =[ ]
In this way every word in the sentence becomes an element in this list and individual operations can be carried out on them
Using the append method and list slicing in the for loop, every word in the sentence is converted to a PIG LATIN

Describe the differences in meaning between the terms relation and relation schema.
Answer:
Relational Schema refers to meta-data elements which are used to describe structures and constraints of data representing a particular domain. A relation abide of a heading and a body. A heading is a set of attributes. A body is a set of n-tuples. The heading of the relation is also the heading of each of its tuples.
Explanation:
Defination of relation:
A relation is a property or predicate that ranges over more than one argument
A relation is defined as a set of n-tuples. In both mathematics and the relational database model, a set is an unordered collection of items. In mathematics, a tuple has an order, and allows for duplication.
Relation schema
A relation schema is a collection of meta-data that describes the relations in a database. Which is also called data base schema. This schema can be described as the “layout” of a database or the blueprint that outlines the way data is organized into table.
A "relation" is a table storing data, while a "relation schema" defines its structure, attributes, and constraints without containing data.
The terms "relation" and "relation schema" are both used in the context of relational databases, but they refer to different concepts:
1. Relation:
- In the context of databases, a relation refers to a table that stores data in rows and columns.
- Each row in a relation represents a record, and each column represents an attribute or field.
- Relations are the fundamental structures in a relational database, and they adhere to certain principles such as each cell containing a single value and rows being unique (no duplicate rows).
- Informally, a relation is often referred to as a table.
2. Relation Schema:
- A relation schema, on the other hand, defines the structure or blueprint of a relation.
- It specifies the name of the relation (table) and the attributes (columns) it contains, along with any constraints or properties associated with those attributes.
- The schema defines the data types of each attribute, any constraints on their values (such as primary keys, foreign keys, or uniqueness constraints), and other properties like nullability.
- The relation schema provides the framework for creating instances of relations (tables) within a database.
- It does not contain any actual data but rather describes the structure and properties of the data that can be stored in a relation.
In summary, while a relation represents the actual data stored in a table, a relation schema defines the structure, attributes, and constraints of that table without containing any data itself. The relation schema serves as a blueprint for creating and understanding relations within a relational database.
The following data segment starts at memory address 0x3600 (hexadecimal)
.data
printString BYTE "Do not add decimal to hex",0
someBytes WORD 19 DUP(0)
moreBytes BYTE 10, 20, 30, 40, 50, 60, 70, 80, 90
questionAddr DWORD ?
ignoreMe WORD ?
What is the hexadecimal address of questionAddr?
Final answer:
To find the hexadecimal address of questionAddr, one adds the sizes of variables declared before it in the data segment starting at 0x3600. After accounting for the bytes used by printString, someBytes, and moreBytes, the address of questionAddr is calculated to be 0x364B.
Explanation:
The question asks for the hexadecimal address of the identifier questionAddr within a data segment that starts at memory address 0x3600. To calculate the address of questionAddr, we must determine the size of the variables declared before it and add that to the starting address. Here is how the memory is allocated for each variable:
printString: The BYTE declaration for the string "Do not add decimal to hex", followed by a null terminator, uses 28 bytes (26 characters + 2 for the double quote and null terminator).
someBytes: The WORD declaration with 19 DUP(0) indicates that space for 19 words is reserved, and since a word is 2 bytes, this gives us 38 bytes.
moreBytes: The BYTE declaration specifies 9 individual bytes.
Adding it all up:
Start Address: 0x3600
+ printString: 28 bytes
+ someBytes: 38 bytes
+ moreBytes: 9 bytes
= Total: 75 bytes
To get the address of questionAddr, convert the total number of bytes to hexadecimal and add it to the start address:
0x3600 + 0x004B (75 in hexadecimal) = 0x364B
Therefore, the hexadecimal address of questionAddr is 0x364B.

Indicate if the following statements are True or False. Statement Circle one Internet Service Providers (ISPs) are proprietary networks.
Answer:
False
Explanation:
Proprietary networks are those that are privately and exclusively managed, controlled and even owned by some organizations.
Internet Service Providers (ISPs) are companies that provide internet access services to companies and consumer products. They allow devices to connect to the internet. They offer much more than just internet access. They also offer related services such as email access, web development and virtual hosting.
ISPs can be open source or proprietary. They could be owned by a community, a firm and even non-profit organizations.
A common preprocessing step in many natural language processing tasks is text normalization, wherein words are converted to lowercase, extraneous whitespace is removed, etc. Write a function normalize(text) that returns a normalized version of the input string, in which all words have been
converted to lowercase and are separated by a single space. No leading or trailing whitespace should be present in the output.
>>> normalize("This is an example.")
'this is an example.'
>>> normalize(" EXTRA SPACE ")
'extra space'
Answer:
def normalize(text):
text = text.lower()
text = text.split()
return text
Explanation:
The functiinfunction is provided with an input text when called upon, then it changes every character in the text into lower case and split each word with a space.
In this new file write a function called swapInts that swaps (interchanges) the values of two integers that it is given access to via pointer parameters. Write a main function that asks the user for two integer values, stores them in variables num1 and num2, calls the swap function to swap the values of num1 & num2, and then prints the resultant (swapped) values of the same variables num1 and num2.
Here is the C++ program to swap the values of two integers. However, let me know if you require the program in some other programming language.
Program:#include <iostream>
/*include is preprocessor directive that directs preprocessor to iostream header file that contains input output functions */
using namespace std;
// namespace is used by computer to identify cout endl cin
void swapInts(int* no1, int* no2) {
/*function swapInts definition which swaps two integer values having pointer type parameters */
int temp; //temporary variable to hold the integer values
temp = *no1; // holds the value at address of no1
*no1 = *no2; //places no2 to no1
*no2 = temp; } //places no2 to temp variable which is holding no1
int main() // enters body of the main function
{ int num1; //declares variable num1 of integer type
int num2; //declares variable num2 of integer type
cout << "Enter two integer values:" << endl;
// prompts the user to input two integer values
cin>>num1; // reads input value of num1
cin>>num2; // reads input value of num2
cout<<"The original value of num1 before swapping is = "<<num1<<endl;
/*displays the original value of integer in num1 variable before calling swapInts function*/
cout<<"The original value of num2 before swapping is = "<<num2<<endl;
/*displays the original value of integer in num2 variable before calling swapInts function*/
swapInts(&num1, &num2);
/*function call to swapInts()) function and here &num1 is address of num1 variable and &num2 is address of num2 variable */
cout << "The swapped value of num1 is = " << num1 << endl;
//displays the value of num1 after swapping
cout << "The swapped value of num2 is = " << num2 << endl; }
//displays the value of num2 integer after swapping
Output:Enter two integer values:
3
5
The original value of num1 before swapping is = 3
The original value of num2 before swapping is = 5
The swapped value of num1 is = 5
The swapped value of num2 is = 3
Explanation:This swapInts(&num1, &num2); statement calls the function swapInts() by passing the addresses of variables num1 and num2 in function call instead of the values of variables.
In simple words the function is called by passing values by pointer. For this purpose the symbol & is used which is called reference operator which is used to assign address of the variables.
So this method is called passing by pointer, which means that address of an actual argument in call to the function is copied to the formal parameters of the called function. The passed argument also gets changed with the change made to the formal parameter.
In void swapInts(int* no1, int* no2) statement no1 holds the address of num1 and no2 holds the address of num2. Also *no1 and *no2 give value stored at addresses num1 and num2.
So to obtain the value which is stored in these addresses, dereference operator "*" is being used with pointer variables *no1 and *no2.
The address of num1 and num2 is passed to this function instead of the values of num1 and num2
Now if any changes are made to *no1 and *no2 this will affect the value of num1 and num2 and their value will be changed too.
"Jointness" and the use of joint forces are underlying themes of the DoD's National Defense Strategy. Which of the following is not a characteristic of a joint force?
a. Fully integrated
b. Adaptable
c. Highly centralized
d. Networked
Answer:
The correct answer is letter "C": Highly centralized.
Explanation:
Jointness is a strategy of the Department of Defense (DoD) in the attempt of combining efforts between the U.S. Military Forces in all stages of operations. With this approach, the Army, Navy, and Air Forces would share resources to help each other while each body would keep its own management.

Assume that you have an array of integers named arr. Which of these code segments print the same results? int i = 0; while (i < arr.length) { System.out.println(arr[i]); i++; } int i; for (i = 0; i <= arr.length; i++) { System.out.println(arr[i]); } for (int i : arr) { System.out.println(i); }
Answer:
2. int i; for (i = 0; i <= arr.length; i++) { System.out.println(arr[i]); }
3. for (int i : arr) { System.out.println(i); }
second and third code segments print the same output.
Explanation:
In first code segment, while loop starts printing from arr[0] and it continues till the second last element of the the array as in statement of while loop i<arr.length. Which print till arr[length - 1].
In second code, for loop starts from 0 and ends at the last element of the array. which prints from arr[0] to arr[length].
In third code segment, it also print from arr[0] to arr[length]. In this case for (int i : arr) means start from first value of array and continues till last element of the array.
Write an app that reads an integer, then determines and displays whether the integer is odd or even. [Hint: Use the remainder operator. An even number is a multiple of 2. Any multiple of 2 leaves a remainder of 0 when divided by 2.]
Answer:
#include <stdio.h>// header file
int main() // main function definition
{
int number; // variable declaration
scanf("%d",&number); // user input for number
if(number%2==0) // check the number to even.
printf("Number is a even number"); // print the message for true value
else
printf("Number is a odd number"); // print the message for false value.
return 0; // return statement.
}
Output:
If the user inputs is 2 then the output is "Number is a even number".If the user inputs is 3 then the output is "Number is a odd number".Explanation:
The above program is to check the even and odd number.The first line of the program is used to include the header file which helps to understand the functions used in the program.Then there is the main function that starts the execution of the program.Then there is a variable declaration of number which is declared as an integer which takes the integer value because the program needs the integer only.Then the scanf function is used to take the inputs from the user.Then the if condition check that the number is divisible by 2 or not.If it is divisible print "even number" otherwise print "odd-number".An app can be written to determine whether an integer is odd or even using the remainder operator in programming.
Explanation:To write an app that determines whether an integer is odd or even, you can use the remainder operator in programming. Here's an example in C++:
#include <iostream>In the above code, the remainder operator % is used to check if the num variable is divisible by 2. If the remainder is 0, then the number is even; otherwise, it is odd.

1. If an F# function has type 'a -> 'b when 'a : comparison, which of the following is not a legal type for it? Select one:
A.(float -> float) -> bool
B.string -> (int -> int)
C.int -> int
D.int list -> bool list
Answer:
B. string -> (int -> int)
Explanation:
We are going to perform comparison operations '->'. It is important to notice that the comparison operation gives us a bool value (True or False) and the comparison operation is legal if and only if the data types to be compared are the same.
Example:
int(4)->int(5) False
int(4)->int(4) True
int(4)->string(4) Error, data types don't match
For this reason:
A. Is legal because float -> float evaluates to True, True is a boolean value and bool -> bool is legal because both are the same data type. B. Is illegal because int -> int evaluates to True, True is a boolean value and string is not a boolean (string -> bool).C. Is legal because int is the same type than int.D. Is legal because the list is the same type than list regardless it's content.Note:
The operations inside parentheses are evaluated first.
List is a type by itself regardless of its content.
The byte-ordering scheme used by computers to store large integers in memory with the high-order byte at the lowest address is called:
a. big endian
b. byte-major
c. little endian
d. byte-minor
Answer:
a. big endian
Explanation:
Endianness determines the order of how the multiple bytes of information are stored in the memory.Big-endian is a byte ordering scheme in which the most significant byte also called the big end of data is stored at the the lowest address. First byte is the biggest so Big-endian order puts most significant byte first and least significant byte in the last. For example: A hexadecimal number 1D23 required two bytes to be represented so in big endian order this hexadecimal number will be represented as 1D 23.Which of the following should get a Page Quality (PQ) rating of Low or Lowest?
Select all that apply.
O A page with a mismatch between the location of the page and the rating location; for example, an English (UK) page for an English (US) rating task.
O A file type other than a webpage, for example: a PDF, a Microsoft Word document, or a PNG file.
O A page that gets a Didn't Load flag.
O Pages with an obvious problem with functionality or errors in displaying content.
Answer:
A page that gets a Didn't Load flag
Pages with an obvious problem with functionality or errors in displaying content
Explanation:
The main reason why a page gets Page Quality rating Low/Lowest is if it can't be shown for one reason or another.
A page with mismatch between the location of the page and the rating location, does have a mismatch but some form of a page is shown.
A file type other than a webpage displays that specific file type in a page framework, so page is shown
Other two do not show a page, so they will get a PQ rating Low/Lowest
Explain why it might be more appropriate to declare an attribute that contains only digits as a character data type instead of a numeric data type.
Final answer:
It may be more appropriate to declare an attribute that contains only digits as a character data type instead of a numeric data type because character data types allow for greater flexibility and can handle other non-numeric characters.
Explanation:
In certain cases, it may be more appropriate to declare an attribute that contains only digits as a character data type instead of a numeric data type. This is because character data types allow for greater flexibility and can handle not only numerical values but also other non-numeric characters.
For example, if you're working with a student ID that consists of digits but also includes special characters like dashes or periods, storing it as a character data type would be more suitable. This way, you can accurately capture and manipulate the entire ID without losing any important characters.
Character data types also allow for better error handling and handling of leading zeros, which can be important in certain scenarios, such as when dealing with bank account numbers or zip codes.
In the case below, the original source material is given along with a sample of student work. Determine the type of plagiarism by clicking the appropriate radio button.Original Source Material:Of course, you could say that free will is an illusion anyway. If there really is a complete theory of physics that governs everything, it presumably also determines your actions. But it does so in a way that is impossible to calculate for an organism that is as complicated as a human being, and it involves a certain randomness due to quantum mechanical effects.Student Version:Like Einstein before him, Hawkings has established himself as a physics superstar. Of particular interest is his work towards a theory of everything. If physics govern everything, a comprehensive theory of physics could also make predictions about how people will act in the future. A precise calculation is, however, impossible in the case of an organism that is as complicated as a human being, and it involves a certain randomness due to quantum mechanical effects.Which of the following is true for the Student Version above?a. Word-for-Word plagiarismb. Paraphrasing plagiarismc. This is not plagiarism
Answer:
c. This is not plagiarism
Explanation:
The student mentions the author when he says "Like Eistein before him, Hawkings has established..."
When yo cite or mention the author of the original text and you paraphrase what he is saying, is not plagiarism, because the reader knows where the author took the idea originally from.
In consequence, when citing the author, the student isn´t making plagiarism.
Final answer:
The student's work constitutes paraphrasing plagiarism because it rephrases the original ideas and maintains the same sentence structure without appropriate attribution.
Explanation:
The student version in question shows signs of paraphrasing plagiarism. This occurs when the sentence structure and the central ideas of the original source material are kept intact while only some words are changed or synonyms are used. In this case, the student has rephrased the original text without proper attribution, maintaining the same structure and ideas presented by the original author about free will and physics but has not credited the source, leading to paraphrasing plagiarism.

Row array userGuess contains a sequence of user guesses. Assign correctGuess with true when myNumber is equal to the user guess.
Answer:
The MATLAB code is given below with appropriate comments
Explanation:
%Define the function.
function correctGuess = EvaluateGuesses(myNumber,userGuess)
%Compute the length.
l = length(userGuess);
%Create an array.
correctGuess = zeros(1, l);
%Begin the loop.
for k = 1: l
%Check the condition.
if myNumber == userGuess(k)
%Update the array correctGuess.
correctGuess(k) = 1;
%End of if.
end
%End of the function.
end
%Call the function.
EvaluateGuesses(3, [3, 4, 5])
Answer:
correctGuess = (myNumber == userGuess);
Explanation:
All you have to do is use the logical operator "==" to signify a relationship between myNumber and userGuess. Whenever the value of myNumber is equal to userGuess, MATLAB will input a "1" into the logical array. It will input a "0" when myNumber does NOT equal userGuess.
Example problem for EvaluateGuesses(3, [3, 4, 5])
correctGuess = (myNumber == userGuess);
The program checks for when 3 is equal to any number in the array userGuess. 3 only equals the first value, so the result is [1, 0, 0].
Therefore, the answer is correctGuess = (myNumber == userGuess);
(This is much simpler than what the other user said... this is most likely what your homework expects you to answer with.)
Write the definition of a method named sumArray that has one parameter, an array of ints. The method returns the sum of the elements of the array as an int.
Answer: Following code is in C++
#include<iostream>
using namespace std;
int sumArray(int a[]) //take array as argument
{
int s=0,i;
for(i=0;i<5;i++)
s+=a[i]; //sums every element
return s;
}
int main() {
int sum,a[]={1,7,4,9,6};
sum=sumArray(a); //calling the function
cout<<"Sum of array is : "<<sum; //printing sum to console
return 0;
}
OUTPUT :
Sum of array is : 27
Explanation:
In the above mentioned code, an array is declared and initialized at the same time. A variable sum of int type stores sum returned the function sumArray() and then it is printed to the console. In the function sumArray(), a variable s of data type int is initialized with value 0 and a loop is executed in which every element of the array is added. At last, s is returned.
Which directive is used when defining 64-bit IEEE long reals?
a. REAL4
b. REAL8
c. REAL64
d. REAL
Final answer:
The directive used to define a 64-bit IEEE long real is 'REAL8', which is used in assembly language programming to allocate 8 bytes of storage for double-precision floating-point numbers. The correct answer is option (b).
Explanation:
You asked which directive is used when defining 64-bit IEEE long reals. The correct option is b. REAL8. This directive is specific to assembly language programming where different 'REAL' types are used to define floating-point numbers of various sizes.
A 64-bit IEEE long real, which is also known as a double-precision floating-point number, is defined with the REAL8 directive in most assemblers. It reserves 8 bytes of memory and can represent very large or very small numbers, much larger or smaller than what can be represented by a single-precision floating-point defined by REAL4 (which reserves 4 bytes).

Develop a spreadsheet that compares the features, initial purchase price, and a two-year estimate of operating costs (paper, cartridges, and toner) for three different color laser printers. Assume that you will print 50 color pages and 100 black-and-white pages each month. Now do the same comparison for three inkjet printers. Write a brief memo on which of the six printers you would choose and why. Develop a second spreadsheet for the same printers, but this time assume that you will print 250 color pages and 500 black-and-white pages per month.
Now which of the printers would you buy and why?
Answer:
dgfdghvcsdhjccxadhhvcsdhjvczafjmbd FYI jjgdc
Final answer:
To compare printers, one must evaluate initial costs and operating expenses for paper, toner, and maintenance. For lower print volumes, an inkjet may be cost-effective, but for higher volumes, a laser printer usually offers better long-term savings, with multi-function printers adding more utility.
Explanation:
To compare the features, initial purchase price, and two-year operating costs of three different color laser printers and inkjet printers, we need to consider several factors. For laser printers, the costs would include the initial cost, and operating costs like paper, cartridges, and toner. For inkjet printers, the costs include the initial cost, ink cartridges, and paper. Operating costs can be significantly influenced by the frequency of printing. We'll also need to anticipate the cost of maintenance and repairs for both types of printers.
Considering the provided printing volumes of 50 color pages and 100 black-and-white pages per month for a low usage scenario, and then 250 color pages and 500 black-and-white pages per month for a high usage scenario, a clear pattern emerges. Laser printers, although more expensive upfront, tend to have lower per-page costs and are more economical for larger print volumes. Conversely, inkjet printers are less expensive initially but can have higher operating costs due to the cost of ink replacements, especially with higher print volumes.
Given these factors, for a lower volume of printing, an inkjet printer might be more cost-effective despite the higher cost of ink. However, for higher volumes, a laser printer is likely to be more cost-efficient in the long run due to the lower cost of toner and its better capability to handle higher volumes efficiently. Additionally, multi-function printers offer added value by combining printing with scanning, faxing, and copying capabilities.
Create an application for a library and name it FineForOverdueBooks. TheMain() method asks the user to input the number of books checked out and the number of days they are overdue. Pass those values to a method named DisplayFine that displays the library fine, which is 10 cents per book per day for the first seven days a book is overdue, then 20 cents per book per day for each additional day.
The library fine should be displayed in the following format:
The fine for 2 book(s) for 3 day(s) is $0.60
(The numbers will vary based on the input.)
Answer:
//The Scanner class is imported which allow the program to receive user input
import java.util.Scanner;
//Class Solution is defined to hold problem solution
public class Solution {
// The main method which signify the begining of program execution
public static void main(String args[]) {
// Scanner object 'scan' is defined to receive input from user keyboard
Scanner scan = new Scanner(System.in);
// A prompt is display asking the user to enter number of books
System.out.println("Please enter number of books: ");
// the user response is assigned to numberOfBook
int numberOfBook = scan.nextInt();
// A prompt is displayed asking the user to enter the number of days over due
System.out.println("Please enter number of days over due: ");
// the user response is assigned to numberOfDaysOverDue
int numberOfDaysOverDue = scan.nextInt();
//displayFine method is called with numberOfBook and numberOfDaysOverDue as arguments
displayFine(numberOfBook, numberOfDaysOverDue);
}
//displayFine method is declared having two parameters
public static void displayFine(int bookNumber, int daysOverDue){
// fine for first seven days is 10cent which is converted to $0.10
double firstSevenDay = 0.10;
// fine for more than seven days is 20cent which is converted to $0.20
double moreThanSevenDay = 0.20;
// the fine to be paid is declared
double fine = 0;
// fine is calculated in the following block
if(daysOverDue <= 7){
//the fine if the over due days is less than or equal 7
fine = bookNumber * daysOverDue * firstSevenDay;
} else{
// the extra days on top of the first seven days is calculated and assigned to extraDays
int extraDays = daysOverDue - 7;
//fine for first seven days is calculated
double fineFirstSevenDays = bookNumber * 7 * firstSevenDay;
// fine for the extradays is calculated
double fineMoreThanSevenDays = bookNumber * extraDays * moreThanSevenDay;
// the total fine is calculated by adding fine for first seven days and the extra days
fine = fineFirstSevenDays + fineMoreThanSevenDays;
}
// The total fine is displayed to the user in a nice format.
System.out.printf("The fine for " + bookNumber + " book(s) for " + daysOverDue + " day(s) is: $%.02f", fine);
}
}
Explanation:
The program first import Scanner class to allow the program receive user input. Then the class Solution was defined and the main method was declared. In the main method, user is asked for number of books and days over due which are assigned to numberOfBook and numberOfDaysOverDue. The two variable are passed as arguments to the displayFine method.
Next, the displayFine method was defined and the fine for the first seven days is calculated first if the due days is less than or equal seven. Else, the fine is calculated for the first seven days and then the extra days.
The fine is finally displayed to the user.
In python
Type two statements. The first reads user input into person_name. The second reads user input into person_age. Use the int() function to convert person_age into an integer. Note: Do not write a prompt for the input values. Below is a sample output for the given program if the user's input is: Amy 4
In 5 years Amy will be 9
Answer:
program:
person_name = input() #input for the name of the person.
person_age = int(input()) #input for the age of the person and convert it into int.
print("In 5 years "+ person_name+" will be "+str(person_age+5)+".") # print the string.
Output:
If the user input is Go and 4 then the output is "In 5 years Go will be 9."Explanation:
The above program is in python language.The first line of the program is used to take the inputs from the user in string format by the help of input function and store it on the variable of person_name.The second line of the program is used to take the input from the user by the help of input function in the form of a string and convert it into an integer by the help of int function and store the value on the person_age.The third line of the program prints the string after adding 5 into person_age because after 5 years the age will be added into 5.The program is meant to be completed in Python. The complete program where comments are used to explain each line is as follows:
#This gets input for first name
person_name = input()
#This gets input for whole number
person_age = int(input())
#This prints the string generated
print('In 5 years,', person_name,'will be',(5+person_age))
The last line of the code uses string concatenation to join the strings before printing the output string

Discuss the importance of user technology security education within organizations. What topics should be included in security education and training?
Answer:
The correct answer should be: "Besides many important topics, 'privacy policies' and 'technology ethics" are two mandatory ones for security education and training".
Explanation:
'Privacy policies' concerning technology is a key for technologies reliability and functionality nowadays for they are patterns to better organize, normatize, and outline how they must work and which are their limits, possibilities, advantages, and disadvantages for technology users. 'Technology ethics' are principles, perspectives, values, and foundations that govern and maintain technology organizations in a reliable and ethical state. All organizations must take care of their employees and educate them concerning their working foundations, policies, and organization. Employees must follow them in order to develop and implement their working foundations and make all things improve and work properly. There are many other topics to be included in security education and training, but these two are the most important ones and must not be left off.

Write a program that prompts the user for the lengths of the two legs of a right triangle, and which reports the length of the hypotenuse. Recall that the hypotenuse length satisfies the formula:
c =√ (a² + b²)
Answer: The following code is in c++
#include <iostream>
#include<math.h>
using namespace std;
int main()
{
float a,b,c;
cout<<"Enter height and base of triangle\n";
cin>>a>>b; //reading two sides from user
c=sqrt(pow(a,2)+pow(b,2)); //calculating hypotenuse
cout<<"Length of hypotenuse is "<<c; //printing third side of triangle
return 0;
}
OUTPUT :
Enter height and base of triangle
3
4
Length of hypotenuse is 5
Explanation:
In the above code, three variables a, b and c of int type are declared. After that, it is asked from user to enter the value of a and b. The user puts the value and then c is calculated with the help of Pythagoras theorem formulae which squares the values of two sides and then adds them to calculate hypotenuse of a right angled triangle and finally c is printed to console.
I want to select between 5 different 2-bit inputs and output it. How many bits do I need to specify which input?
Answer:
3 select inputs are required to select a specific input between 5 inputs.
Explanation:
Multiplexer is used to select the inputs from different inputs to a single output. There are many types of multiplexers for different number of inputs selection. 1. 2x1 is the type of multiplexer where 2 inputs and 1 output. This is used to select between these inputs. There is one more pin to select the input between these two inputs that is called select input.
2. Another type is 4x1 multiplexer. There are 4 inputs and one output. In this type of multiplexer 2 select pins are used for selection of input bits between these 4 inputs.
For more than 4 inputs and less than 8 inputs, 8x1 multiplexer is used. this multiplexer uses three inputs for selection purpose.
