You are asked by your supervisor to export NPS configuaration from a server. Your supervisor contacts you and tells you it is missing the log files. What must you do to provide your supervisor with the NPS log files?
Answer:
You must import the NPS configurations, then manually cnfigure the SQL Server Logging on the target machine.
Explanation:
The SQL Server Logging settings are not in anyway exported. If the SQL Server Logging was designed on the root machine, the a manually configure of SQL Server Logging has to be done on the target machine after the NPS configurations must have been imported.
Although administrator rights is needed at least to import and export NPS settings and configurations, while that isn’t the issue in this case. NPS configurations are moved to a XML file that is non-encrypted by default. There is no wizard or tool whatsoever to export or import the configuration files.
In the lab, you wrote a four-paragraph __________ that summarized your findings, described the approach and prioritization of critical, major, and minor risk assessment elements, included a risk assessment and risk impact summary of the seven domains of a typical IT infrastructure, and provided recommendations and next steps for executive management.
a.management overview
b.risk assessment outline
c.IT infrastructure recap
Answer:
b
Explanation:
Write the routines with the following declarations: void permute( const string & str ); void permute( const string & str, int low, int high ); The first routine is a driver that calls the second and prints all the permutations of the characters in string str. If str is "abc", then the strings that are output are abc, acb, bac, bca, cab, and cba. Use recursion for the second routine.
Answer:
Here is the first routine:
void permute( const string &str ) { // function with one parameter
int low = 0;
int high = str.length();
permute(str, low, high);
}
Or you can directly call it as:
permute(str, 0, str.length());
Explanation:
The second routine:
void permute( const string &str, int low, int high)
//function with three parameters
{ string str1 = str;
if ( low == high ) { //base case when last index is reached
for (int i = 0; i <= high; ++i)
cout << str1[i]; } //print the strings
else {
for (int i=low; i<high; ++i) { // if base case is not reached
string temp = str1; //fix a character
swap( str1[i], str1[low] ); //swap the values
permute( str1, low + 1, high ); //calling recursive function (recursion case)
swap( str1[i], str1[low] ); } } } //swap again to go to previous position
In this function the following steps are implemented:
A character is fixed in the first position.
Rest of the characters are swapped with first character.
Now call the function which recursively repeats this for the rest of the characters.
Swap again to go to previous position, call the recursive function again and continue this process to get all permutations and stop when base condition is reached i.e. last index is reached such that high==low which means both the high and low indices are equal.
You can write a main() function to execute these functions.
int main() {
string str;
cout << "Enter a string: ";
cin >> str;
permute(str); }
Final answer:
The question requires defining two routines to output all permutations of a given string. The first function 'permute' serves as a driver, while the second 'permute' function is a recursive method that systematically swaps characters to produce each permutation.
Explanation:
Routines to Permute a String:
The task is to write routines to generate all permutations of the characters in a given string. The first function serves as a driver, while the second function uses recursion to perform the actual permutation process.
void permute(const string &str) {
permute(str, 0, str.size() - 1);
}
void permute(const string &str, int low, int high) {
if (low == high) {
cout << str << endl;
} else {
for (int i = low; i <= high; i++) {
// Swap the current index with the low element
swap(str[low], str[i]);
// Recursively call permute on the substring
permute(str, low + 1, high);
// Swap back for the next iteration
swap(str[low], str[i]);
}
}
}
In the above code, permute(const string &str) is the driver function that calls the recursive function permute(const string &str, int low, int high), initiating the process with the full range of the string (from index 0 to the length of the string minus one).
Within the recursive function, when the low index matches the high index, it indicates that a permutation has been generated, and it gets printed. If not, the function enters a for-loop, where recursive calls are made after swapping the current character with the one at the start of the substring defined by low and high. After the recursive call returns, the characters are swapped back to their original position, allowing for correct generation of subsequent permutations.
A __________ grants the authority to perform an action on a system. A __________ grants access to a resource. right, permission login, password permission, right password, login
Answer:
A right grants the authority to perform an action on a system. A permission grants access to a resource.
Explanation:
In System administration there are different rights and permissions are given to the user as per the requirement to perform some actions and accessing some resources.
Rights are given to the users may be at admin level to perform some action or make some changes in the system. The users who have rights of the system can add, edit or delete data from the system as per requirement of the company.
Many peoples granted by permissions by providing them some passwords to access the resources of the systems. These users did not have the right to change, add, edit or delete any data. They just can use the information.
A right grants the authority to perform an action on a system. A permission grants access to a resource.
In the context of system security and access control:
- A right is a privilege granted to a user or process that allows them to perform a specific action on a system. For example, a right might allow a user to shut down the computer or to modify system settings.
- A permission is a rule that grants access to a specific resource, such as a file, directory, or network resource. Permissions determine what actions (such as read, write, or execute) can be performed on that resource.
Thus, a right defines the actions a user can perform, while a permission defines what resources a user can access and what they can do with those resources.
Define function multiply(), and within the function: Get user input() of two strings made of whole numbers Cast the input to int() Multiply the integers and return the equation with result as a str()
Answer:
str(int(input("enter the vale of first whole number: "))*int
(input("Enter the value of the second whole number: ")))
Explanation:
boom this works bc it does boom
In response to the question, a conceptual code example for a multiply() function has been provided where user input is taken, cast to int, multiplied, and the result is returned as a string.
The question asks to define a multiply() function in a programming context, specifically to use user input, cast string to int, perform multiplication, and return the result as a string. Here is a conceptual example of how you might write such a function:
def multiply():The multiply() function first captures two strings from the user, converts them into integers, multiplies them, and then returns the equation with the result as a string.
c++ design a class named myinteger which models integers. interesting properties of the value can be determined. include these members: a int data field named value that represents the integer's value. a constructor that creates a myinteger object with a specified int value. a constant getter that returns the value
Answer:
#include <iostream>using namespace std;class myinteger { private: int value; public: myinteger(int x){ value = x; } int getValue(){ return value; } };int main(){ myinteger obj(4); cout<< obj.getValue(); return 0;}Explanation:
Firstly, we use class keyword to create a class named myinteger (Line 5). Define a private scope data field named value in integer type (Line 7 - 8).
Next, we proceed to define a constructor (Line 11 - 13) and a getter method for value (Line 15 -17) in public scope. The constructor will accept one input x and set it to data field, x. The getter method will return the data field x whenever it is called.
We test our class by creating an object from the class (Line 23) by passing a number of 4 as argument. And when we use the object to call the getValue method, 4 will be printed as output.
Read the Security Guide about From Anthem to Anathema on pages 238-239 of the textbook. Then answer the following questions in the format on an essay. Create a heading for each question. Questions: Think about all of the cloud services you use. How vulnerable are you right now to having your data stolen
Answer:
Answer explained below
Explanation:
Think about all of the cloud services you use. How vulnerable are you right now to having your data stolen?
At its most basic level, “the cloud” is just fancy talk for a network of connected servers. (And a server is simply a computer that provides data or services to other computers). When you save files to the cloud, they can be accessed from any computer connected to that cloud’s network.
The cloud is not just a few servers strung together with Cat5 chords. Instead, it’s a system comprised of thousands of servers typically stored in a spaceship-sized warehouse—or several hundred spaceship-sized warehouses. These warehouses are guarded and managed by companies capable of housing massive loads of data, including the likes of Google (Google Docs), Apple (iCloud), and Dropbox.
So, it’s not just some nebulous concept. It’s physical, tangible, real.
When you save files to the cloud, you can access them on any computer, provided it’s connected to the Internet and you’re signed into your cloud services platform. Take Google Drive. If you use any mail, you can access Drive anywhere you can access your email. Sign in for one service and find your entire library of documents and photos in another.
Why are people concerned with cloud security?
It’s physically out of your hands.
You aren’t saving files to a hard drive at your house. You are sending your data to another company, which could be saving your data thousands of miles away, so keeping that information safe is now dependent on them. “Whether data is being sent automatically (think apps that sync to the cloud) or driven by users uploading photos to social media, the end result is that it’s all there somewhere being logged and stored,” says Jérôme Segura, Senior Security Researcher at Malwarebytes.
And that somewhere is a place that’s not in your direct control.
Risks of cloud storage
Cloud security is tight, but it’s not infallible. Cyber gurus can get into those files, whether by guessing security questions or bypassing passwords. That’s what happened in The Great iCloud Hack of 2014, where unwanted pictures of celebrities were accessed and published online.
But the bigger risk with cloud storage is privacy. Even if data isn’t stolen or published, it can still be viewed. Governments can legally request information stored in the cloud, and it’s up to the cloud services provider to deny access.

Consider the following architecture. 1 cache block = 16 words. Main memory latency is the time delay for each data transfer, which = 10 memory bus clock cycles. A memory transfer time = 1 memory bus clock cycle, which is also called bandwidth time. For any memory access, it consists of latency time plus the bandwidth time. The cache miss penalty is the time to transfer one block from main memory to the cache. In addition, it takes 1 clock cycle to send the address to the main memory. Compute the miss penalty for the following configurations. Configuration (a): Requires 16 main memory accesses to retrieve a cache block and words of the block are transferred one at a time. Configuration (b): Requires 4 main memory accesses to retrieve a cache block and words of the block are transferred four at a time. Configuration (c): Requires 4 main memory accesses to retrieve a cache block and words of the block are transferred one at a time.
Answer:
The answers are A)176 B)44 C)56.
Explanation:
According to the information given in the question about the architecture that is used and its communication times;
For option A: The goal is to retrieve one cache block which consists of 16 words. Doing this one word at a time over a period of 16 main memory accesses and the miss penalty for this configuration is 10*16 = 160 bus clock cycles for data transfer and 1*16 = 16 bus clock cycles for memory transfer time which comes up to 176.
For option B: The goal is to retrieve one cache block which consists of 16 words. Doing this four words at a time over a period of 4 main memory accesses and the miss penalty for this configuration is 10*4 = 40 bus clock cycles for data transfer and 1*4 = 4 bus clock cycles for memory transfer which comes up to 44.
For option C: The goal is to retrieve one cache block which consists of 16 words. Doing this 4 words at a time over a period of 4 main memory accesses and the miss penalty for this configuration is 10*4 = 40 bus clock cycles for data transfer and 1*16 = 16 bus clock cycles for memory transfer since words of the block are transferred not 4 but 1 at a time which comes up to 56.

Develop a Python program. Define a class in Python and use it to create an object and display its components. Define a Student class with the following components (attributes): Name Student number Number of courses current semester
Answer:
class Student: def __init__(self, Name, Student_Num, NumCourse): self.Name = Name self.Student_Num = Student_Num self.NumCourse = NumCourse s1 = Student("Kelly", 12345, 4) print(s1.Name) print(s1.Student_Num) print(s1.NumCourse)Explanation:
Firstly, use the keyword "class" to create a Student class.
Next, create a class constructor (__init__) that takes input for student name, student number and number of course (Line 2) and assign the input to the three class attributes (Line 3-5). All the three class attributes are preceded with keyword self.
Next, create a student object (Line 7) and at last print all the attributes (Line 8-10).

A university begins Year 1 with 80 faculty. They hire 4 faculty each year. During each year 10% (rounded to the nearest integer) of the faculty present at the beginning of the year leave the university. For example, in a year where there are 73 faculty at the beginning of the year, 7 would leave the university at the end of the year. The university wants to know how many faculty they will have at the end of year 10. The resulting spreadsheet can be found below. In cell G9 the first cell address referred to was cell E9.

Write a recursive function that has an argument that is an array of characters and two arguments that are the bounds (inclusive) on array indices. The function should reverse the order of those entries in the array whose indices are between the two bounds. For example, if the array is a[0]: ‘A’ a[1]: ‘B’ a[2]: ‘C’ a[3]: ‘D’ a[4]: ‘E’ and the bounds are 1 and 4, then, after the function is run the array elements should be a[0]: ‘A’ a[1]: ‘E’ a[2]: ‘D’ a[3]: ‘C’ a[4]: ‘B’ Consider the following declaration for your function: void flipArray( char arr[], unsigned int from, unsigned int to ); Test your code before writing it out. You may safely assume that from and to are valid indices with respect to arr.
Answer:
Here is the C++ program:
#include <iostream> // for input output functions
using namespace std; // to identify objects like cin cout
/* recursive function to reverse the order of array elements between two bound of array indices */
void flipArray(char arr[], unsigned int from, unsigned int to) {
if (from >= to) // base case
return;
swap(arr[from], arr[to]);
//function to swap characters according to specified values in from and to
flipArray(arr, from + 1, to - 1); } // recursive function call
int main() { //start of main() function body
int size; //stores the number of elements in array
cout<<"Enter the size of the array: "; // prompts user to enter array size
cin>>size; // reads array size from user
char array[size]; // array of size specified by user
cout<<"Enter the characters: "; //prompts user to enter elements in array
// loop to take input characters in array according to specified size
for (int i = 0; i < size; ++i)
{cin >> array[i];} // reads array elements from user
unsigned int i,j; // stores values of two bounds of indices
cout<<"Enter the two bounds of array indices:";
// prompts user to enter two bounds of array indices
cin>>i>>j; //reads array indices from user
//displays original array elements
cout << "The original array is: "<<array<< endl;
flipArray(array,i,j); //calls flipArray() function
cout << "Array after flip from "<< i<<"to "<<j<<" is: "<<array << endl; }
/*displays elements of array after reversing array characters according to bounds of array indices */
Explanation:
The program is explained in the given comments with every statement. Lets understand the logic of the recursive function for the input array that has characters: A B C D E and two bounds 1 and 4 i.e. from B to E
First the base condition if (from >= to) is checked. Here the value of from is 1 and value of to is 4. So the base condition evaluates to false as 1 < 4So the program control moves to the next statement: swap(arr[from], arr[to]); which swaps the array characters from the two indices 1 and 4.
arr [1] = B, arr [4] = E
So B and E are swapped.
A E C D B
Next statement: flipArray(arr, from + 1, to - 1); is a call to recursive function flipArray,
from + 1 = 1+1 = 2 So now the from index moves one position ahead
to - 1 = 4 - 1 = 3 So now the to index moves one position behind
So new value of from = 2 and to = 3
The base condition is check again which evaluates to false as 2<3The swap() function swaps the elements at indices 2 and 3 which means:
arr[2] = C
arr[3] = D
So C and D are swapped.
A E D C B
Next is the call to recursive function flipArray()
from + 1 = 2 + 1 = 3
to - 1 = 3 - 1 = 2
So the value of from = 3 and value of to = 2
Now the base condition is checked again and it evaluates to true as 3>2So this is the stop condition.
Hence the array after flip is:
A E D C B

Your supervisor manages the corporate office where you work as a systems analyst. Several weeks ago, after hearing rumors of employee dissatisfaction, he asked you to create a survey for all IT employees. After the responses were returned and tabulated, he was disappointed to learn that many employees assigned low ratings to morale and management policies.
This morning he called you into his office and asked whether you could identify the departments that submitted the lowest ratings. No names were used on the individual survey forms. However, with a little analysis, you probably could identify the departments because several questions were department-related.
Now you are not sure how to respond. The expectation was that the survey would be anonymous. Even though no individuals would be identified, would it be ethical to reveal which departments sent in the low ratings? Would your supervisor’s motives for wanting this information matter?
Maintaining confidentiality in employee surveys is essential to ensure honest feedback and protect employee trust. Identifying departments with low morale raises ethical considerations, particularly when the survey was intended to be anonymous.
Workplace Confidentiality and Ethical Dilemmas
When managing confidential employee surveys, such as an attitude survey, it is crucial to maintain the confidentiality of employees' responses. This is important for cultivating trust and fostering an environment where employees feel safe to express genuine concerns. The ethical dilemma arises when considering whether to identify departments with low morale based on non-anonymized data, which could breach confidentiality agreements and potentially erode trust. The intention behind identifying these departments is a crucial element to consider: if it's for the purpose of targeted improvements without repercussions, it may be more justifiable than if it were for punitive measures.
Organizational behavior research argues for the importance of maintaining confidentiality to get honest responses and the negative impacts when surveys lead to no action. Actionability from survey results is key, but it must respect the promised confidentiality. This also relates to issues of social desirability bias, where respondents may skew their answers to appear more favorable when anonymity isn't assured. Trust both in the confidentiality and the constructive use of survey data is vital for the ongoing success of such workplace assessments.
Any effort to identify departments from the survey data should be carefully weighed against ethical considerations, and if pursued, it should be done transparently and with a clear, constructive action plan to address the issues without targeting individuals.
You have been asked to write a two-page report that explains the extent to which the IT department can configure the cryptographic features of Word 2010. What is the process involved in configuring encryption?
Answer:Encryption is the process
of translating plain text data into something that appears to be random and meaningless. A symmetric key is used during both the encryption and decryption process. To decrypt a particular piece of ciphertex, the key that was used to encrypt the data must be used.
Types of encryption
1.Symmetric encryption :This is also known as public key encryption. In symmetric encryption, there is only one key, and all communication patties use the same key for encryption and decryption.
2.Asymmetric encryption :This is foundational technology for SSL(TLS)
How encryption is being configured
Encryption uses algorithms to scramble your information. It is then transmitted to the receiving party, who is able to decode the message with a key.
Explanation:
Write a script that will:
• Call a function to prompt the user for an angle in degrees.
• Call a function to calculate and return the angle in radians. (Note: π radians = 180°)
• Call a function to print the resultWrite all of the functions, also. Put the script and all functions in separate code files.
Answer:
The solution code is written in Python:
import math def getUserInput(): deg = int(input("Enter an angle in degree: ")) return deg def calculateRad(deg): return (deg * math.pi) / 180 def printResult(deg, rad): print(str(deg) + " is equal to " + str(round(rad,2)) + " radian") degree = getUserInput() radian = calculateRad(degree) printResult(degree, radian)Explanation:
Since we need a standard Pi value, we import math module (Line 1).
Next, create a function getUserInput to prompt user to input degree (Line 3-5).
Next, create another function calculateRad that take one input degree and calculate the radian and return it as output (Line 7-8).
Create function printResult to display the input degree and its corresponding radian (Line 10-11).
At last, call all the three functions and display the results (Line 13-15).
def c_to_f(): # FIXME return # FIXME: Finish temp_c = float(input('Enter temperature in Celsius: ')) temp_f = None # FIXME: Call conversion function # temp_f = ?? # FIXME: Print result # print('Fahrenheit:' , temp_f)
Answer:
def c_to_f(celsius): return celsius * 9/5 + 32 temp_c = float(input('Enter temperature in Celsius: ')) temp_f = None temp_f = c_to_f(temp_c) print('Fahrenheit:' , temp_f)Explanation:
The first piece of code we can fill in is the formula to convert Celsius to Fahrenheit and return it as function output (Line 2).
The second fill-up code is to call the function c_to_f and pass temp_c as argument (Line 7). The temp_c will be processed in the function and an equivalent Fahrenheit value will be returned from the function and assigned it to temp_f.
Create a class named College Course that includes data fields that hold the department (for example, ENG), the course number (for example, 101), the credits (for example, 3), and the fee for the course (for example, $360). All of the fields are required as arguments to the constructor, except for the fee, which is calculated at $120 per credit hour. Include a display () method that displays the course data. Create a subclass named Lab Course that adds $50 to the course fee. Override the parent class display () method to indicate that the course is a lab course and to display all the data. Write an application named UseCourse that prompts the user for course information. If the user enters a class in any of the following departments, create a LabCourse: BIO, CHM, CIS, or PHY. If the user enters any other department, create a CollegeCourse that does not include the lab fee. Then display the course data. Save the files as CollegeCourse.java, LabCourse.java, and UseCourse.java.

So far we have worked on obtaining individual digits from 4 digits of 5 digit numbers. The added them to find the sum of digits. However, now we know about the loop and we can remove the limit of having a specific number of digits. Write a program to print out all Armstrong numbers between 1 and n where n will be an user input. If the sum of cubes of each digit of the number is equal to the number itself, then the number is called an Armstrong number. For example, 153 = (1 * 1* 1)+ ( 5 * 5* 5 ) + ( 3*3*3) In order to solve this problem we will implement the following function: sumDigitCube(): write a function sumDigitCube() that takes a positive integer as a parameter and returns the sum of cube of each digit of the number. Then in the main function, take an integer n as input and generate each number from 1 to n and call the sumDigitCube() function. Based on the returned result, compares it with the value of the generated number and take a decision and print the number if it is Armstrong number
Answer:
#include<stdio.h>
int sumDigitCube(int n);
int main(){
int n, i;
printf("Enter number: ");
scanf("%d", &n);
printf("The Armstrong numbers are:" );
for(i=1; i<=n; i++){
if(sumDigitCube(i)==i){
printf(" %d", i);
}
}
printf("\n");
return 0;
}
int sumDigitCube(int n){
int s = 0;
int digit;
while(n>0){
digit = n%10;
s += digit * digit *digit;
n = n/10;
}
return s;
}
Explanation:
Write a function, named "wait_die_scheduler" that takes a list of actions, and returns a list of actions according to the following rules. The actions given to the scheduler will only consist of WRITE and COMMIT actions. (Hence only exclusive locks need be implemented.) Each transaction will end with a COMMIT action. Before examining each action, attempt to perform an action for each of the transactions encountered (ordered by their names). After all the actions have been examined, continue to attempt to perform an action from each transaction until there are no more actions to be done. You will need to add LOCK, UNLOCK, and ROLLBACK actions to the list of actions to be returned, according to the Wait-Die protocol. If releasing more than one lock (for instance after a COMMIT), release them in order by the name of their object. Use the deferred transaction mode (only requesting locks when needed).
To implement the `wait_die_scheduler` function according to the Wait-Die protocol for handling WRITE and COMMIT actions in transactions, we'll simulate a scheduler that ensures correct behavior with respect to locks and transaction order. The Wait-Die protocol is used to manage concurrency and handle conflicts between transactions efficiently. Below is a Python implementation of this scheduler function:
def wait_die_scheduler(actions):
# Data structures to track locks and actions
locks = {} # Dictionary to track locks by object name
results = [] # List to collect final actions to be returned
# Process the list of actions
for action in actions:
transaction_name = action[0]
action_type = action[1]
object_name = action[2]
# If action is WRITE or COMMIT
if action_type == 'WRITE' or action_type == 'COMMIT':
# Check if the transaction already has a lock on the object
if object_name in locks and locks[object_name] != transaction_name:
# Conflict detected, need to resolve based on Wait-Die protocol
# Check order of transactions for waiting or aborting
if transaction_name < locks[object_name]:
# Current transaction waits (older transaction, so wait)
results.append((transaction_name, 'WAIT', object_name))
else:
# Current transaction aborts (newer transaction, so abort)
results.append((transaction_name, 'ROLLBACK', object_name))
# Release locks held by the aborted transaction
results.extend([(locks[obj], 'UNLOCK', obj) for obj in sorted(locks.keys())])
locks.clear() # Clear all locks after rollback
else:
# No conflict, acquire lock for the transaction
locks[object_name] = transaction_name
# Add the original action to the results
results.append((transaction_name, action_type, object_name))
# If action is COMMIT, release locks held by the committed transaction
if action_type == 'COMMIT':
results.extend([(locks[obj], 'UNLOCK', obj) for obj in sorted(locks.keys())])
locks.clear() # Clear all locks after commit
# Final pass to release any remaining locks (should not normally occur)
results.extend([(locks[obj], 'UNLOCK', obj) for obj in sorted(locks.keys())])
locks.clear() # Clear all locks after processing all actions
return results
# Example usage
actions = [
('T1', 'WRITE', 'A'),
('T2', 'WRITE', 'B'),
('T1', 'COMMIT', 'A'),
('T2', 'COMMIT', 'B'),
('T1', 'WRITE', 'B'),
('T1', 'COMMIT', 'B')
]
result_actions = wait_die_scheduler(actions)
for action in result_actions:
print(action)
Explanation of the `wait_die_scheduler` function:
1. Initialization: We start by defining empty data structures (`locks` and `results`) to track locks on objects and the resulting list of actions.
2. Processing Actions: Iterate through each action in the provided list (`actions`). Each action is a tuple consisting of transaction name, action type (`WRITE` or `COMMIT`), and the object name.
3. Handling WRITE and COMMIT Actions:
- For a `WRITE` action:
- Check if the transaction already holds a lock on the object.
- If there's a conflict (another transaction holds the lock), resolve it based on the Wait-Die protocol by either making the current transaction wait or aborting it.
- For a `COMMIT` action:
- Release all locks held by the committed transaction.
4. Building Resulting Actions:
- Append the original action to the `results` list.
- If a transaction commits or aborts, add corresponding `UNLOCK` actions for all locks held by the transaction.
5. Final Cleanup: Ensure all locks are released after processing all actions.
This implementation follows the Wait-Die protocol by managing locks, resolving conflicts between transactions, and ensuring correct order of operations according to the protocol rules. Adjustments may be needed based on specific requirements or variations of the Wait-Die protocol for different scenarios.
An odometer is the gauge on your car that measures distance traveled. In the United States, an odometer measures in miles; elsewhere else, it measures kilometers. Many vehicles with electronic odometer interfaces can switch between miles and kilometers. Something to consider: if an odometer gets replaced, a new one must be able to be set to some specified mileage. a) Write an Odometer class which must include the following methods: • _init__, _str_1_repr__, overloaded add and substract method The constructor must take two arguments mileage, and any other specification that uses units (you choose the unit specification) . Both arguments must have a default value (you may choose the default values) O Addition and subtraction both have one odometer operand and one numeric operand, where the numeric operand represents the miles being added/subtracted (not two odometer operands). o Addition should be commutative (but not subtraction). o Output methods should always be rounded to 1/10 mile (kilometer), but the odometer itself should maintain full floating-point accuracy. b) Include sample code that uses your class and demonstrates the use of all methods as well as demonstrating error handling. c) at the end of your code show an illustrated run of your code "W" "
Answer:
class Odometer():
def __init__(self, mileage=0, unit='miles'):
if mileage < 0:
raise ValueError('Mileage cannot be in negative')
self.mileage = mileage
if unit in ['miles', 'kilometers']:
self.units = unit
else:
raise ValueError("Miles and kilometer unit are allowed only")
def __repr__(self):
return self.__str__()
def __str__(self):
return 'Mileage: {:.1f} {}'.format(self.mileage, self.units)
def add(self, odometer, distance):
if odometer.units == self.units:
self.mileage = odometer.mileage + distance
elif self.units == 'miles':
self.mileage = odometer.mileage / 1.6 + distance
else:
self.mileage = odometer.mileage * 1.6 + distance
def subtract(self, odometer, distance):
if odometer.units == self.units:
self.mileage = odometer.mileage + distance
elif self.units == 'miles':
self.mileage = odometer.mileage / 1.6 - distance
else:
self.mileage = odometer.mileage * 1.6 - distance
honda_odometer = Odometer(100.56, 'miles')
print('Reading of Honda odometer:', honda_odometer)
new_odometer = Odometer(100, 'kilometers')
print('Reading of New odometer:', new_odometer)
new_odometer.add(honda_odometer, 10)
print('Reading of New odometer after adding honda odometer:', new_odometer)
new_odometer.subtract(honda_odometer,20)
print('Reading of New odometer after subtracting honda odometer:', new_odometer)
Explanation:
Create a class only supports miles and kilometers as units .Create the add method that accepts an odometer, distance and adds it to the current object .Create the subtract method that accepts an odometer and distance and subtract it to the current object .The two mathematical models of language description are generation and recognition. Describe how each can define the syntax of a programming language.
Answer:
The correct answer to the following question will be "Semantic and Syntax error".
Explanation:
Syntax error:
Corresponds to such a mistake in a pattern sentence structure that is composed in either a specific language of that same coding. Because computer programs have to maintain strict syntax to execute appropriately, any elements of code that would not adhere to the programming or scripting language syntax can result inside a syntax error.
Semantic error:
That would be a logical error. This is because of erroneous logical statements. Write inaccurate logic or code of a program, which results incorrectly whenever the directives are implemented.
So, it's the right answer.
In Java, variables of the super class class can point to objects of the subclass. For example, if Student is a super class to Athletes, then any variable (say s) of type Student can point to either Student or Athlete objects. Sometimes we want to know exactly whether s is pointing to Student or pointing to Athlete. This can be accomplished with an if statement. Complete the missing part in the following if statement so it prints YES if the variable s is currently pointing to an Athlete if (s ____________ Athlete) System.out.print("YES");
Answer:
"instanceof" is the correct answer for the above question.
Explanation:
The "instanceof" is a statement in java, which is used to check for an object that any object is derived from that class or not. The syntax of this statement is "object instanceof class name". If the object is derived from declared class, then it will result in true or otherwise it will result in false.The above question asked about that condition which is used to check that the s object is derived from the Athlete class or not so when the if condition blanks will fill from the "instanceof", then the user will get the if condition which can check. Hence "instanceof" is the correct answer.
