Question

Write a linux program that implements the c-scan disk scheduling algorithms. we assume that the disk arm moves upwards(towards the edge) initially.

The program takes two inputs

- the starting position

- a disk request file

the program generates two outputs

- The schedule sequence

- The total disk seek distance

disk request file

test

assume your program is called iosched

1. to run the program

$iosched 2000 disk-reqeust-file

2069,2296,....

total disk seek distance is nnnnn

Explanation / Answer

#include #include #include #include using namespace std; int compare (const void * a, const void * b) { if ( *(int*)a < *(int*)b ) return -1; if ( *(int*)a == *(int*)b ) return 0; if ( *(int*)a > *(int*)b ) return 1; } void shift(int a[],const int size) { for(int i=1;i100) goto enter_request_number; current_location: coutrequest[0]; sorted_request[0]=request[0]; if(request[0]>max||request[0]
