print("\nIs age == '27'? I predict False.")
print(age == '27')
this:sex = 'Male'
print("Is sex == 'Female'? I predict True.")
print(sex == 'Female')
print("\nIs sex == 'Female'? I predict False.")
print(sex == 'Joy')
this:level = 'College'
print("Is level == 'High School'? I predict True.")
print(level == 'High School')
print("\nIs level == 'College'? I predict False.")
print(age == 'College')
Conditions 1 and 2 test for name and age
Both conditions are true
Hence, true values are returned
Conditions 3 and 4 tests for sex and level
Both conditions are false
Hence, false values are returned.
Conditional tests in Python allow you to check if a certain condition is True or False. Here are four examples of conditional tests with predictions and code outputs.
Explanation:Conditional Tests in PythonConditional tests in Python allow you to check if a certain condition is True or False. They are often used in decision-making structures like if statements. Here are four examples of conditional tests:
age = 16
print('Is age greater than 18? I predict False.')
print(age > 18)
temperature = 25
print('Is temperature between 20 and 30? I predict True.')
print(20 < temperature < 30)
is_raining = False
print('Is it not raining? I predict True.')
print(not is_raining)
name = 'John'
print('Does name start with J? I predict True.')
print(name.startswith('J'))
These examples demonstrate how to use conditional statements in Python to check if certain conditions are True or False, and then execute different code based on the results.

Here are the steps. (1) Create a Student class containing an ID, a last name, and a list of course names such as "COP2210" or "COP2250". This should not be a string of multiple courses. The ID should be an integer which is printed with leading zeros. (2) Create a class named StudentTest that contains a List of students. Do not use the list provided here. In the class constructor, create 15 students and add them to the list. Each student's ID must be different. Each student you add to the list must contain 2-4 different course names. At least one should have two course names and at least one should have four course names. Make sure the students do not all have the same courses, although there should be some overlap (see the sample below). The student names must be inserted into the list in random order (not sorted). (3) Sort the list in ascending order by student last name and display the list. For each student, display the ID with leading zeros, last name, and list of courses on a single line. Here is sample output. Note how the tab character is inserted after the name to line up the next column containing courses. Be sure there is no trailing comma at the end of the list of courses.

Print person1's kids, call the incNumKids() method, and print again, outputting text as below. End each line with a newline.Sample output for below program with input 3:Kids: 3New baby, kids now: 4// ===== Code from file PersonInfo.java =====public class PersonInfo { private int numKids; public void setNumKids(int setPersonsKids) { numKids = setPersonsKids; } public void incNumKids() { numKids = numKids + 1; } public int getNumKids() { return numKids; }}// ===== end =====// ===== Code from file CallPersonInfo.java =====import java.util.Scanner;public class CallPersonInfo { public static void main (String [] args) { Scanner scnr = new Scanner(System.in); PersonInfo person1 = new PersonInfo(); int personsKid; personsKid = scnr.nextInt(); person1.setNumKids(personsKid); /* Your solution goes here */ }}// ===== end =====
Answer:
System.out.println("Kids: " + person1.getNumKids());
person1.incNumKids();
System.out.println("New baby, kids now: " + person1.getNumKids());
Explanation:
Reminder: To be able to call a function that is inside a class, we need to use an object of that class. In this case, person1 is our object. If we would like to access any function, we need to type person1.functionName().
1) We need to call getNumKids() to get how many kids they have (It is 3 because user inputs 3 and it is set to the this value using setNumKids() function). To call this function, we need to use person1 object that is created earlier in the main function. To be able to print the result, we call the function inside the System.out.println().
2) To increase the number of kids, we need to call incNumKids() method with person1 object again. This way number of kids are increased by one, meaning they have 4 kids now.
3) To get the current number of kids, we need to call getNumKids() function using person1 object. To be able to print the result, we call the function inside the System.out.println().
Answer:
System.out.println("Kids: " + person1.getNumKids());
person1.incNumKids();
System.out.println("New baby, kids now: " + person1.getNumKids());

Write a statement that outputs variable userNum. End with a newline.
Answer:
System.out.println(userNum);
Explanation:
Using Java programming language, lets assume the variable userNum is entered by a user. The code snippet below will prompt the user to enter a number and output the the variable:
import java.util.Scanner;
public class TestClass {

A large organization with a large block address (12.44.184.0/21) is split into one medium size company using the block address (12.44.184.0/22) and two small organizations. If the first small company uses the block (12.44.188.0/23), what is the remaining block that can be used by the second small company? Explain how the datagrams destined for the two small companies can be correctly routed to these companies if their address blocks still are part of the original company.
Answer:
The answer is explained below
Explanation:
The Organization mask is 21 so number of addresses granted to organization are 32 - 21 = 2048 addresses
Now, medium-size company has mask as 22 so number of addresses to medium-size organization are 32 - 22 = 1024 addresses
Each small organization has 32 - 23 = 512 addresses as mask is 23
That implies the range of addresses for each organization
Large Organization = 12.44.184.0/21 - 12.44.191.255/21
Medium organization = 12.44.184.0/22 - 12.44.187.255/22
small Organization 1: 12.44.188.0/23 - 12.44.189.255/23
small Organization 2: 12.44.190.0/23 - 12.44.181.255/23
so now if we have a router then we need to configure it so that when an address is routed correctly.
So router should be installed or configured for forward lookup which are defined in forwarding table
The forwarding table is configured o bases of longest prefix match
So Forward table will be:
00001100 00101100 10111110 small organization1
00001100 00101100 10111111 small organization2
00001100 00101100 1011110 medium-size organization
For each of them we can take an example in the range of its IP address and check this forwarding table will correctly identify the other inner organizations

Assign to maxSum the max of (numA, numB) PLUS the max of (numY, numZ). Use just one statement. Hint: Call findMax() twice in an expression.
import java.util.Scanner;
public class SumOfMax {
public static double findMax(double num1, double num2) {
double maxVal = 0.0;
// Note: if-else statements need not be understood to
// complete this activity
if (num1 > num2) { // if num1 is greater than num2,
maxVal = num1; // then num1 is the maxVal.
}
else { // Otherwise,
maxVal = num2; // num2 is the maxVal.
}
return maxVal;
}
public static void main(String [] args) {
double numA = 5.0;
double numB = 10.0;
double numY = 3.0;
double numZ = 7.0;
double maxSum = 0.0;
/* Your solution goes here */
System.out.print("maxSum is: " + maxSum);
return;
}
}
Answer:
maxSum=findMax(numA,numB)+findMax(numY,numZ);
Explanation:
In the above statement, a function is used twice to calculate the maximum of 2 numbers passed as parameters of type double and returns the maximum value of type double as well. As the function is static, so, there is no need to make an object of the class in which the function is made. After finding the largest of both the pairs, the values are added and printed to console.
Answer:
maxSum = findMax(numA, numB); // first call of findMax
maxSum = maxSum + findMax(numY, numZ); // second call

out: [0, 10, 20, 10]
b)
int: [8, 2, 9, 7, -1, 55]

c)
int: [0, 16, 9, 1, 64, 25, 25, 14]
out: [0, 0, 0, 0, 16, 9, 64, 25]
Explanation:
What the code is doing is changing the list if and only if the item number i, where i is an odd position on the list, is greater than the item number i-1. If the condition mentioned is satisfied, the element number i is removed, and a zero is added to the beginning of the list; this is why the dimension of the input is equal to the output (for every element removed a zero is added).
Note:
The first item of a list is the item 0.add method can receive two parameters the first indicating the position where the element will be added and the second the element to be added. .get method allows you to select any element on the list by its index..size method gives you the size of the listIn the for loop i += 2 indicates an increment of two, since we start with i = 1 we are going to iterate through odd numbers i = 1,3,5,7...
Evaluate the expression. Be sure to list a value of appropriate type (e.g., 7.0 rather than 7 for a double, Strings in quotes). 19 / 2 / 2.0 + 2.5 * 6 / 2 + 0.5 * 4
14.0
Explanation:Using the level of precedence in Java,
From left to right;
(i) the first division operation will be done.
(ii)followed by the second division operation.
(iii)followed by the first multiplication operation.
(iv)followed by the third division operation.
(v)followed by the second multiplication operation.
(vi) followed by the first addition operation.
(vii)lastly followed by the second addition operation.
=================================================
Taking the steps above one after the other;
(i) the first division operation will be done (i.e 19 / 2)
=> Integer division in Java gives an integer result. Therefore, 19 / 2 = 9.5 will give 9.
So,
=> 19 / 2 / 2.0 + 2.5 * 6 / 2 + 0.5 * 4
=> 9 / 2.0 + 2.5 * 6 / 2 + 0.5 * 4
(ii)followed by the second division operation. (i.e 9 / 2.0)
=> From the result from step (i), the second division operation is now 9 / 2.0.
=> 9 / 2.0 = 4.5
So,
=> 9 / 2.0 + 2.5 * 6 / 2 + 0.5 * 4
=> 4.5 + 2.5 * 6 / 2 + 0.5 * 4
(iii)followed by the first multiplication operation. (i.e 2.5 * 6)
=> The first multiplication operation is given by 2.5 * 6
=> 2.5 * 6 = 15.0
So,
=> 4.5 + 2.5 * 6 / 2 + 0.5 * 4
=> 4.5 + 15.0 / 2 + 0.5 * 4
(iv)followed by the third division operation. (i.e 15.0 / 2)
=> The third division operation is given by 15.0 / 2
=> 15.0 / 2 = 7.5
So,
=> 4.5 + 15.0 / 2 + 0.5 * 4
=> 4.5 + 7.5 + 0.5 * 4
(v)followed by the second multiplication operation. (i.e 0.5 * 4)
=> The second multiplication operation is given by 0.5 * 4
=> 0.5 * 4 = 2.0
So,
=> 4.5 + 7.5 + 0.5 * 4
=> 4.5 + 7.5 + 2.0
(vi) followed by the first addition operation. (i.e 4.5 + 7.5)
=> The first addition operation is given by 4.5 + 7.5
=> 4.5 + 7.5 = 12.0
So,
=> 4.5 + 7.5 + 2.0
=> 12.0 + 2.0
(vii) lastly followed by the second addition operation. (i.e 12.0 + 2.0)
=> The second addition operation is given by 12.0 + 2.0
=> 12.0 + 2.0 = 14.0
So,
=> 12.0 + 2.0
=> 14.0
Therefore, 19 / 2 / 2.0 + 2.5 * 6 / 2 + 0.5 * 4 = 14.0
Note:In Java, the order of precedence for arithmetic operators is;
=> /, * and %
=> followed by + and -

It takes in the smart card, and with the command, retrieves the bank account information addressed on the card. The cashier types the total price of purchased product and it is automatically minus and updated on the account database. Then the invoice of the transaction is issued to the customer.
Suppose you are a project manager who typically has been using a waterfall development-based methodology on a large and complex project. Your manager has just read the latest article in Computerworld that advocates replacing this methodology with the Unified Process and comes to you requesting you to switch. What do you say?
Answer:
Answer explained below
Explanation:
Depending upon the current situation we can switch. That means suppose the entire project is mid way that means we already implemented the project by Waterfall methodology then it would take lot of time to switch to Prototype model. Again if we see the efficiency I mean if we complete the project using prototype model and the outcome would be very well and robust then we should definitely switch to prototype model. So depending on the scenario we need to decide whether it would be beneficial to switch or not.
Further, we have the differences between Waterfall and Prototype :
I) In case of Waterfall model requirements should be very well known. On the other hand in case of prototype model if the user requirements are not complete then we can choose prototype model.
II) Technical issues should be cleared in case of Waterfall model, on the other hand technical requirements need not be clear.
Advantages of Waterfall:
I) Easy to understand this model and easy to use.
II) It provides structure to inexperienced staff
III) Milestones are well understood
IV) Set requirements stability
Disadvantages of Waterfall Model:
I) All requirements must be known upfront
II) Inhibits flexibility
III) Can give a false impression of progree
Advantage of Prototype Model:
I) Even if user requirements are not complete we can use
II) Even if technical issues are not clear we can use
Disadvantage of Prototype:
I) The Model is complex
II) Risk Assessment expertise is required
III)Time spent for evaluating risks too large for small projects.
Get three int values from the keyboard. Using the conditional operator determine if the numbers are in ascending order. If they are in ascending order store the character ‘A’ in a char variable otherwise store a ‘D’ character in the char variable. Do not duplicate assignment operations.
Answer:
Program:
First_number = int(input("Enter first number")) # The first number is entered by the user.
second_number = int(input("Enter second number")) # The second number is entered by the user.
third_number = int(input("Enter Third number")) # The Third number is entered by the user.
if(First_number<second_number)and(second_number<third_number):# compare the first number with second number and the second number with the third number.
store ='A' # assign the 'A' value on store variable.
else:
store= 'D' # Assign the D value on store variable.
Output:
If the user inputs 4,5,6 then store variable holds 'A'.If the user inputs 6,5,4 then store variable holds 'D'.Explanation:
The above program is written in python language in which the first, second and the third line of the program is used to rendering the message to the user and take the inputs from the user and stored the value on First_number, second_number, and third_number after converting the value on int.Then the fourth line of the program is used to compare that the first number and second number are in ascending order or not and it also checks that the second number and third number are in ascending order or not. Then assign the 'A' character for the store variable if both the condition is true because it is separated by 'and' operator which gives true if both the condition is true.Otherwise, assign the 'D' character on the store variable.Final answer:
To check if three int values are in ascending order and assign 'A' or 'D' to a char variable accordingly, use the conditional operator in a single line of code after obtaining the int values from the user.
Explanation:
To determine if three integer values are in ascending order using the conditional operator, you can perform a comparison between them. If you have three variables, let's call them num1, num2, and num3, the ascending order condition would be num1 < num2 and num2 < num3. If this condition is true, the character 'A' is assigned to a character variable; otherwise, the character 'D' is assigned. With the conditional operator, it would look something like this:
char order = (num1 < num2 && num2 < num3) ? 'A' : 'D';
This single line checks the condition and assigns 'A' to order if the numbers are in ascending order, or 'D' if they are not. It's important to ensure that you retrieve the integer values from the keyboard correctly and store them in the variables num1, num2, num3 before evaluating the conditional expression.
a user reports that his dot matrix printer is printing dark and clear on the left of the paper but that the print is very light on the right side of the paper. what should you do to correct this problem with the printer
Answer:
Correctly position the platen of the printer to hold the paper in place.
Explanation:
Since the dot matrix printer is printing dark and clear on the left of the paper but very light on the right side of the paper, it is possible that the paper is not being held properly. So adjusting the platen will hold the paper properly and hence uniform prints on the paper.
Note: Dot matrix printers are printers that print closely related dots to form require texts (shapes) by striking some pins against an ink ribbon.
Some of the parts of these printers are; power supply, carriage assembly, Paper sensor, ribbon, platen and pins.
Given the multiplication 65535 x 32768, will the result cause overflow on a 32-bit system? Will the result need more than 32 bits to be stored in?
Answer:
65535 x 32768 =214 7450880
which is in the range of 32 bit unsigned integers, so there will be no overflow and we wont be in a need of more bits than 32 bit.
Explanation:
An overflow error indicates that software attempted to write down data beyond the bounds of memory.
Each program features a section of memory allocated for a stack. The stack is employed to store internal data for the program and is extremely fast and keep track of return addressing. A program may jump to a neighborhood that reads some data from the disk drive, then it returns from that routine to continue processing the info. The stack keeps track of the originating address, and therefore the program uses that for the return. Kind of like leaving breadcrumbs to seek out your way back. The stack features a limited amount of space for storing. If software attempts to access a neighborhood of the stack beyond its limits, an overflow error occurs.
• signed 32-bit integers support the range [-2147483648,2147483647]
• unsigned 32-bit integers support the range [0,4294967295]
And if you go outside this range, even temporarily, you would like to be very careful. Most cases handle the overflow technically and provide you "wraparound" or "modulo" behavior where carry bits outside the range just disappear and you're left with the low-order bits like the precise result.
In computer architecture of 32 bit, memory addresses, or other data units are those who are 32 bits (4 octets) wide. Also, 32-bit CPU and ALU architectures are those who have supported registers, address buses, or data buses of that size. 32-bit microcomputers are computers during which 32-bit microprocessors are the norm.
Which of the following instructions should be allowed only in kernel mode? (a) Disable all interrupts. (b) Read the time-of-day clock. (c) Set the time-of-day clock. (d) Change the memory map.
Answer:
A, B and D
Explanation:
The kernel is the central core of the computer's operating system, that has total control of all the activities of the computer. The kernel is a very small program in memory and runs first during the boot of the system. It is the interactive link between the hardware and operating system and other system softwares.
The uses a command line to receive and execute command for various system configurations like storage and memory mapping, enable and disable interrupts, set timers or allocate time slice to run programs etc.
Write a program that prompts the user to enter seven test scores and then prints the average test score. (Assume that the test scores are decimal numbers.)
Answer:
The cpp program for the scenario is given below.
#include <iostream>
using namespace std;
int main() {
// array to store seven test scores
double scores[7];
// variable to store sum of all test scores
double sum=0;
// variable to store average of all test scores
double avg_score;
// user is prompted to enter seven test scores
cout<<"Enter the test scores ";
// user input is taken inside for loop
// for loop executes seven times to take input for seven test scores
for(int j=0; j<7; j++)
{
cin>>scores[j];
sum = sum + scores[j];
}
// average of test scores is calculated and assigned
avg_score = sum/7;
cout<<"The average of all entered test scores are "<< avg_score <<endl;
return 0;
}
OUTPUT
Enter the test scores 90
88
76
65
56.89
77.11
68
The average of all entered test scores are 74.4286
Explanation:
The program execution is explained below.
1. An array, scores, is declared of size seven to store seven user-entered test scores.
2. Variables, sum and avg_score, are declared to store the sum and average of all the seven test score values. The variable sum is initialized to 0.
3. User is prompted to enter the test scores using cout keyword.
4. Inside for loop, all seven test scores are stored inside array, scores, using cin keyword.
5. Inside the same for loop, the values in the array, scores, are added and assigned to the variable sum.
6. Outside the for loop, the average score is calculated and assigned to the variable avg_score.
7. At the end, the average score is displayed. New line is inserted using endl after the average score is displayed.
8. In order to store decimal values, all variables and the array are declared with double datatype.
9. The main() has return type of integer and thus, ends with a return statement.
10. The iostream is included to enable the use of keywords like cin, cout, endl and others.
Write a complete C program to run on the MSP432 platform to do the following:
Declare an array of size 3 x 7 of type uint8_t. Use loops to initialize each array element to contain the value of the sum of its indices (e.g., for element arr[2][5], write a value of 7 to arr[2][5], write a value of 7 to arr[1][6], etc.). Use additional loops to go through the array and test each value – if a value is not a multiple of 5, add that value to a cumulative sum and write a zero to the array element. If it is a multiple of 5, leave it untouched. Print the final result as a 16-bit integer value (the sum of the array elements not multiples of 5). Be sure to compile it in CCS to catch any syntax errors.
Answer:
The C code is given below with appropriate comments
Explanation:
#include <stdio.h>
int main()
{
//array declaration
int arr[3][7], cumulativeSum = 0;
//initialize the array
for(int i=0; i<3; i++)
{
for(int j=0; j<7; j++)
{
arr[i][j] = i+j;
}
}
//calculate the cumulative sum
for(int i=0; i<3; i++)
{
for(int j=0; j<7; j++)
{
if((arr[i][j] % 5) != 0)
{
cumulativeSum += arr[i][j];
arr[i][j] = 0;
}
}
}
//display the final array
printf("The final array is: \n\n");
for(int i=0; i<3; i++)
{
for(int j=0; j<7; j++)
{
printf("%d ", arr[i][j]);
}
printf("\n");
}
//display the cumulative sum
printf("\nCumulative Sum = %d", cumulativeSum);
return 0;
}

How do you freeze the total cell so that it doesn't change when copied?
a) put a # in front of the letter and number that represents the cell position.
b) put a $ behind the letter and number that represents the cell position.
c) put a $ in front of the letter and number that represents the cell position.
d) you don't do anything, they are already frozen in Excel"
Answer:
c) put a $ in front of the letter and number that represents the cell position.
Explanation:
Dollar sign ($) is used to lock the formula in the cell. This is called absolute reference. In this type of referencing, A dollar sign is place in front of the letter and number to lock that cell. Whenever we copy that cell, the formula will be copied in other cell without changing its reference number.
As
Example 1
C1 = A1 + B1
if we copy this formula in C2 then it becomes
C2= A2 + B2
there both reference of A and B has been changed.
Example 2
If we put $ sign as
C1= $A$1 + $B$1
now of we copy C1 and into C2
C2= $A$1 + $B$1
There reference of cell is not changed.
To freeze a cell in Excel, use the dollar sign ($) in front of the letter and number of the cell position. For example, if the total cell is A1, change it to $A$1. This technique ensures Excel maintains the cell reference when copying the formula.
Explanation:To freeze a total cell in Excel so that it doesn't change when copied, you should use the dollar sign ($) in front of the letter and number that represent the cell position. This operation is commonly referred to as cell referencing. For instance, if your total cell is A1, you would change it to $A$1 to freeze it.
The dollar sign instructs Excel to maintain the reference to the specific cell when you copy the formula to other cells. Without the dollar sign, Excel will adjust the formula to refer to relative cells. Therefore, option (c) is the correct technique for freezing the total cell in Excel.
