编写C程序模拟实现单处理机系统中的进程调度算法，实现对多个进程的调度模拟，要求采用最短剩余时间优先算法,进行模拟调度。

好的，我会根据您的要求编写一个C程序模拟实现单处理机系统中的进程调度算法，采用最短剩余时间优先算法进行模拟调度。

以下是代码：

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

#define MAX_PROCESS 10

typedef struct Process {
    int pid;
    int arrival_time;
    int burst_time;
    int remaining_time; // 剩余需要运行的时间
    int waiting_time; // 等待时间
    int turnaround_time; // 周转时间
    int completed; // 是否完成
} Process;

void printGanttChart(Process processes[], int n) {
    int i, j;
    int total_time = 0;
    int time = 0;
    int burst_time[MAX_PROCESS] = { 0 };
    int completion_time[MAX_PROCESS] = { 0 };

    // 初始化剩余时间和等待时间
    for (i = 0; i < n; i++) {
        processes[i].remaining_time = processes[i].burst_time;
        processes[i].waiting_time = 0;
        processes[i].turnaround_time = 0;
        processes[i].completed = 0;
        total_time += processes[i].burst_time;
    }

    printf("\n");

    while (time < total_time) {
        // 选择最短剩余时间的进程
        int min_time = 999999;
        int min_index = -1;
        for (i = 0; i < n; i++) {
            if (processes[i].arrival_time <= time && processes[i].completed == 0) {
                if (processes[i].remaining_time < min_time) {
                    min_time = processes[i].remaining_time;
                    min_index = i;
                }
            }
        }

        if (min_index == -1) {
            printf("|");
            time++;
            continue;
        }

        // 执行进程
        printf("| P%d ", processes[min_index].pid);
        burst_time[min_index]++;
        time++;
        processes[min_index].remaining_time--;

        // 更新等待时间
        for (i = 0; i < n; i++) {
            if (processes[i].arrival_time <= time && processes[i].completed == 0 && i != min_index) {
                processes[i].waiting_time++;
            }
        }

        // 检查进程是否完成
        if (processes[min_index].remaining_time == 0) {
            processes[min_index].completed = 1;
            completion_time[min_index] = time;
        }
    }

    printf("|\n");

    // 计算等待时间和周转时间
    int total_waiting_time = 0;
    int total_turnaround_time = 0;
    for (i = 0; i < n; i++) {
        processes[i].turnaround_time = completion_time[i] - processes[i].arrival_time;
        processes[i].waiting_time = processes[i].turnaround_time - processes[i].burst_time;
        total_waiting_time += processes[i].waiting_time;
        total_turnaround_time += processes[i].turnaround_time;
    }

    // 输出结果
    printf("\nProcess\tArrival Time\tBurst Time\tWaiting Time\tTurnaround Time\n");
    for (i = 0; i < n; i++) {
        printf("P%d\t%d\t\t%d\t\t%d\t\t%d\n", processes[i].pid, processes[i].arrival_time, processes[i].burst_time, processes[i].waiting_time, processes[i].turnaround_time);
    }
    printf("\nAverage waiting time: %f\n", (float)total_waiting_time / n);
    printf("Average turnaround time: %f\n", (float)total_turnaround_time / n);
}

int main() {
    int n, i;
    Process processes[MAX_PROCESS];

    // 输入进程信息
    printf("Enter the number of processes: ");
    scanf("%d", &n);
    printf("Enter the arrival time and burst time of each process:\n");
    for (i = 0; i < n; i++) {
        printf("P%d: ", i + 1);
        processes[i].pid = i + 1;
        scanf("%d %d", &processes[i].arrival_time, &processes[i].burst_time);
    }

    // 执行进程调度算法
    printGanttChart(processes, n);

    return 0;
}

该程序使用了一个结构体来表示进程，并实现了最短剩余时间优先算法进行进程调度。程序会首先输入每个进程的到达时间和执行时间，然后输出进程的调度图和等待时间、周转时间等统计信息。

希望这个程序能够满足您的需求。
