用C语言写一个同时实现时间片轮转调度算法和静态优先级调度算法的代码，可自定义时间片的大小和优先级高低

好的，我可以帮你实现这个代码。首先，我们需要定义进程控制块（PCB）的结构体，其中包括进程ID、进程状态、优先级、剩余时间片等信息。

#define MAX_PROCESS_NUM 10

typedef enum{
    READY, RUNNING, BLOCKED
} ProcessState;

typedef struct{
    int pid;
    ProcessState state;
    int priority;
    int remain_time_slice;
} PCB;

PCB processes[MAX_PROCESS_NUM];
int process_num = 0;

接下来，我们需要实现两种调度算法。时间片轮转算法的思路是将每个进程依次执行一个时间片，如果该进程在时间片结束前未执行完，则将其挂起，等待下一次调度。静态优先级调度算法则是按照优先级高低依次执行进程。

#define TIME_SLICE 3

void time_slice_scheduling(){
    int i;
    do{
        for(i = 0; i < process_num; i++){
            if(processes[i].state == RUNNING){
                processes[i].remain_time_slice--;
                if(processes[i].remain_time_slice == 0){
                    processes[i].state = READY;
                }
            }
            if(processes[i].state == READY){
                processes[i].state = RUNNING;
                processes[i].remain_time_slice = TIME_SLICE;
            }
        }
    }while(1);
}

void priority_scheduling(){
    int i, j, max_priority, max_index;
    do{
        max_priority = -1;
        max_index = -1;
        for(i = 0; i < process_num; i++){
            if(processes[i].state == READY && processes[i].priority > max_priority){
                max_priority = processes[i].priority;
                max_index = i;
            }
        }
        if(max_index != -1){
            processes[max_index].state = RUNNING;
            for(j = 0; j < process_num; j++){
                if(j != max_index && processes[j].state != BLOCKED){
                    processes[j].state = READY;
                }
            }
        }
    }while(1);
}

最后，我们需要编写主函数，创建进程并调用两种不同的调度算法。

#include <stdio.h>

int main(){
    // 创建进程并初始化
    processes[0].pid = 0;
    processes[0].state = RUNNING;
    processes[0].priority = 2;
    processes[0].remain_time_slice = TIME_SLICE;

    processes[1].pid = 1;
    processes[1].state = READY;
    processes[1].priority = 1;
    processes[1].remain_time_slice = 0;

    processes[2].pid = 2;
    processes[2].state = READY;
    processes[2].priority = 3;
    processes[2].remain_time_slice = 0;

    process_num = 3;

    // 调用时间片轮转调度算法
    time_slice_scheduling();

    // 调用静态优先级调度算法
    priority_scheduling();

    return 0;
}

当然，以上代码只是一个简单的示例，你可以根据自己的需要进行修改和扩展。
