The output is 21 because c is incremented by 3 until it surpasses 10 and the value of c is added to sum each time the loop runs.

I hope this helps!

Requests to access specific cylinders on a disk drive arrive in this order: 24, 20, 4, 40, 6, 38, and 12, and the seek arm is in

GarryVolchara [31]

Answer:

The time required to seek using First come,first served algorithm is 876 milliseconds.

The time required to seek using Shortest Seek Time First algorithm is 360 milliseconds.

The time required to seek using LOOK (initialing moving upwards) algorithm is 348 milliseconds.

Explanation:

Part a,b : First-come, first-served:

The order of the cylinders is as 10, 22, 20, 2, 40, 6, 38

10 + 12 + 2 + 18 + 38 + 34 + 32 = 146 cylinders = 876 milliseconds.

ii) Shortest Seek Time First:

The order of the cylinders is as 20, 22, 10, 6, 2, 39, 40

0 + 2 + 12 + 4 + 4 + 36 + 2 = 60 cylinders = 360 milliseconds.

iii) LOOK (initialing moving upwards):

The order of the cylinders is as 20, 22, 38, 40, 10, 6, 2

0 + 2 + 16 + 2 + 30 + 4 + 4 = 58 cylinders = 348 milliseconds.

Answer:

#include<iostream>

using namespace std;

//main function

int main(){

//nested for loop

for(int i=9;i>=1;i--){

for(int j=1;j<=i;j++){

cout<<j<<" "; //display

}

return 0;

}

Explanation:

Include the library iostream for using the input/output instruction in the c++ programming.

Create the main function and takes nested for loop. Nested for loop means, for loop inside the another for loop.

For every value of outside for loop, inside for loop execute.

we make outer for loop in decreasing format, means it start from 9 and goes to 1 and inside for loop make in increasing format, means loop start from 1 and it goes to that value which is provided by the outer loop.

and print the output for every cycle.

Lets dry run the code:

the outer loop starts from 9 and it checks the condition 9>=1, condition true. then the program moves to the inner loop which starts from 1 and goes to the 9.

first, it also checks the condition 1 <= 9, condition true and prints the number from 1 to 9.

then, i is reduced by 1. it means i become 8.

then, the above process continues from 1 to 8 and so on...

the loop process will terminate if the outer loop terminate.

Finally, we get the output.
