Non-preemptive Shortest Job First (SJF) scheduling policy is not optimal if:
ivann1987 [24]

Answer:

The answer is A

Explanation:

Basically, Shortest job first (SJF) is a scheduling policy that selects jobs on queue for execution  within a short execution time.

From the definition of SJF above, it means that there are a lot of process on queue and the (SJF) job is to receive processes on queue to execute within a short execution time.

Therefore, if all the jobs or process arrives at the SJF at the same time, the SJF will forfeit one of its major purpose which is scheduling of jobs.

That will therefore not make Non-preemptive Shortest Job First (SJF) not function at its optimal point.

Create a lottery game application. Generate three random numbers (see Appendix D for help in doing so), each between 0 and 9. Al
Pachacha [2.7K]

The question is not complete! Here is the complete question and its answer!

Create a lottery game application. Generate three random numbers (see Appendix D for help in doing so), each between 0 and 9. Allow the user to guess three numbers. Compare each of the user’s guesses to the three random numbers and display a message that includes the user’s guess, the randomly determined three-digit number, and the amount of money the user has won as follows:

no matches: 0

any one matching: 10$  

two matching: 1000$  

three matching: 100000$  

Code with Explanation:

#include <iostream>

using namespace std;

int main()

{

int matches=0;

int guess_1, guess_2, guess_3;

int num_1, num_2, num_3;

// get 3 digits from the user

cout<<"Enter first guess digit 0 to 9"<<endl;

cin>>guess_1;

cout<<"Enter second guess digit 0 to 9"<<endl;

cin>>guess_2;

cout<<"Enter third guess digit 0 to 9"<<endl;

cin>>guess_3;

// every time program runs srand() generates new random numbers and rand()%10 makes sure that number is single digit 0 to 9

srand(time(NULL));

num_1=rand()%10;

cout<<"First lottery digit: "<<num_1<<endl;

num_2=rand()%10;

cout<<"Second lottery digit: "<<num_2<<endl;

num_3=rand()%10;

cout<<"Third lottery digit: "<<num_3<<endl;

// store random generated numbers and guess numbers in arrays to compare them

int num[3]= {num_1,num_2,num_3};

int guess[3]={guess_1,guess_2,guess_3};

// compare the arrays to find out how many are matching

   for(int i=0; i<3; i++)

   {

 for(int j=0; j<3; j++)

 {

  if(num[i]==guess[j])

  {    

   matches = matches + 1;

  }

 }

}

cout << "Total Matches are: " <<matches << endl;

// display reward according to the number of matches

if (matches==0)

cout<<"you won: $0"<<endl;

if (matches==1)

cout<<"you won: $10"<<endl;

if (matches==2)

cout<<"you won: $1000"<<endl;

if (matches==3)

cout<<"you won: $100000"<<endl;

return 0;

}

Output:

Enter first guess digit 0 to 9

7

Enter second guess digit 0 to 9

1

Enter third guess digit 0 to 9

5

First lottery digit: 3

Second lottery digit: 7

Third lottery digit: 2

Total Matches are: 1

You won: $10

Enter first guess digit 0 to 9

7

Enter second guess digit 0 to 9

3

Enter third guess digit 0 to 9

4

First lottery digit: 5

Second lottery digit: 4

Third lottery digit: 7

Total Matches are: 2

You won: $1000
