磁盘调度算法模拟c语言

以下是一个使用FCFS算法模拟磁盘调度的C语言程序：

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

#define MAX 1000

int main()
{
    int n, i, head, sum = 0, disk[MAX];
    float avg;

    printf("Enter the number of disk locations: ");
    scanf("%d", &n);

    printf("Enter the initial position of the disk head: ");
    scanf("%d", &head);

    printf("Enter the disk queue:\n");
    for(i = 0; i < n; i++)
        scanf("%d", &disk[i]);

    printf("\n");

    printf("The disk queue is: ");
    for(i = 0; i < n; i++)
        printf("%d ", disk[i]);

    printf("\n\n");

    printf("The disk head starts at %d\n", head);

    for(i = 0; i < n; i++)
    {
        sum += abs(head - disk[i]);
        head = disk[i];
    }

    printf("\nTotal number of track movements = %d\n", sum);
    avg = (float)sum / n;
    printf("Average track movements = %.1f\n", avg);

    return 0;
}
