Five jobs arrive nearly simultaneously for processing and their estimated CPU cycles are, respectively: Job A = 2 ms, Job B = 12 ms, Job C = 15 ms, Job D = 7 ms, and Job E = 3 ms.

Using FCFS, in what order would they be processed? What is the total time required to process all five jobs? What is the average turnaround time for each of these five jobs?

Answers

Answer 1

This is an example with solution:

Five jobs arrive nearly simultaneously for processing and their estimated CPU cycles are, respectively: Job A = 12, Job B = 2, Job C = 15, Job D = 7, and Job E = 3 ms.

a. Using FCFS, and assuming the difference in arrival time is negligible, in what order would they be processed? What is the total time required to process all five jobs? What is the average turnaround time for all five jobs?

Answer: The order of processing for the given jobs = A->B->C->D->E.

Total time needed to process all the jobs = 12+2+15+7+3 = 39 ms.

Turn around time for job A = 12 ms.

Turn around time for job B = 15 ms.

Turn around time for job C = 30 ms.

Turn around time for job D = 37 ms.

Turn around time for job E = 40 ms.

Answer : Therefore, the average turnaround time = (12+15+30+37+40)/5 = 26.8 ms.

Answer 2

Order of processing is A, B, C, D, E and Total time to process and Average turnaround time is 39 ms and 24 ms

Turnover time and order of processing:

Order of processing = A, B, C, D, E

Total time to process all five jobs = Job A + Job B + Job C + Job D + Job E

Total time to process all five jobs = 2 + 12 + 15 + 7 + 3

Total time to process all five jobs = 39 ms

Average turnaround time = [(2-0) + (2+12-0) + (2+12+15-0) + (2+12+15+7-0) + (2+12+15+7+3-0)] / 5

Average turnaround time = (2+14+29+36+39) / 5

Average turnaround time = 24 ms

The program should use variables, cout, cin, getline(), type casting, and output manipulators. The user should enter the name of the student and scores ranging from 0 to 100 (integer) for each grading item. The final score is the sum of all grading items. The average score is the average of all grading items.

Explanation:

The required parameters such as cin, cout, etc. implies that the program is to be written in C++ (not C).

So, I answered the program using C++.

Line by line explanation is as follows;

This declares name as character of maximum size of 100 characters

char name[100];

This declares the grading items as float

float classp, test, assgn, exam, prctscore,ave;

This prompts the user for student name

cout<<"Student Name: ";

This gets the student name using getline

cin.getline(name,100);

This prompts the user for class participation. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)

cout<<"Class Participation: "; cin>>classp;

while(classp <0 || classp > 100){  cout<<"Class Participation: "; cin>>classp; }

This prompts the user for test. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)

cout<<"Test: "; cin>>test;

while(test <0 || test > 100){  cout<<"Test: "; cin>>test; }

This prompts the user for assignment. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)

cout<<"Assignment: "; cin>>assgn;

while(assgn <0 || assgn > 100){  cout<<"Assignment: "; cin>>assgn; }

This prompts the user for examination. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)

cout<<"Examination: "; cin>>exam;

while(exam <0 || exam > 100){  cout<<"Examination: "; cin>>exam; }

This prompts the user for practice score. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)

cout<<"Practice Score: "; cin>>prctscore;

while(prctscore <0 || prctscore > 100){  cout<<"Practice Score: "; cin>>prctscore; }

This calculates the average of the grading items

ave = (int)(classp + test + assgn + exam + prctscore)/5;

This prints the calculated average

cout <<setprecision(1)<<fixed<<"The average score is "<<ave;

Answers

Answer:

Here is the Python program:

user_tweet = input()

decoded_tweet = user_tweet.replace('TTYL', 'talk to you later')

print(decoded_tweet)

Explanation:

The program works as follows:

Suppose the input is:    'Gotta go. I will TTYL'

This is stored in user_tweet. So

user_tweet = 'Gotta go. I will TTYL'

The statement: user_tweet.replace('TTYL', 'talk to you later')  uses replace() method which is used to replace a specified string i.e. TTYL with another specified string i.e. talk to you later in the string stored in user_tweet.

The first argument of this method replace() is the string or phrase that is to be replaced and the second argument is the string or phrase that is to replace that specified string in first argument.

So this new string is assigned to decoded_tweet, after replacing 'TTYL' with 'talk to you later' in user_tweet.

So the print statement print(decoded_tweet) displays that new string.

Hence the output is:

Gotta go. I will talk to you later.

The method of a file object inputs a line of text and returns it as a string, including the newline is readLine. Thus, option D is correct.

What is object inputs?

The Object Input interface adds object reading to the Data Input interface. Data Input contains primitive type input methods; Object Input expands that interface to accommodate objects, arrays, and Strings.

The ReadLine function takes a line from either the standard input stream and returns it. (For a definition of a line, read the paragraph below the list.) This implies that if the default input device is a keyboard, the ReadLine function will be blocked until the user pushes the Enter key.

Therefore, it can be concluded that option D is correct.
