将时间片轮船和银行家算法结合，用C语言编写一个简单的代码

好的，以下是一个简单的时间片轮转调度算法与银行家算法结合的C语言代码：

#include <stdio.h>
#include <stdbool.h>

#define MAX_PROCESSES 10
#define MAX_RESOURCES 5

int available[MAX_RESOURCES];
int allocation[MAX_PROCESSES][MAX_RESOURCES];
int max[MAX_PROCESSES][MAX_RESOURCES];
int need[MAX_PROCESSES][MAX_RESOURCES];
int work[MAX_RESOURCES];
bool finish[MAX_PROCESSES];

void init() {
    // 初始化资源可用数量
    for (int i = 0; i < MAX_RESOURCES; i++) {
        printf("请输入第 %d 种资源的可用数量：", i + 1);
        scanf("%d", &available[i]);
    }

    // 初始化进程的资源分配和最大需求
    for (int i = 0; i < MAX_PROCESSES; i++) {
        printf("请输入进程 %d 的资源分配情况：", i + 1);
        for (int j = 0; j < MAX_RESOURCES; j++) {
            scanf("%d", &allocation[i][j]);
        }
        printf("请输入进程 %d 的最大需求：", i + 1);
        for (int j = 0; j < MAX_RESOURCES; j++) {
            scanf("%d", &max[i][j]);
            need[i][j] = max[i][j] - allocation[i][j];
        }
        finish[i] = false;
    }
}

bool is_safe(int process) {
    for (int i = 0; i < MAX_RESOURCES; i++) {
        if (need[process][i] > work[i]) {
            return false;
        }
    }
    return true;
}

bool safe_sequence(int sequence[MAX_PROCESSES], int *length) {
    // 初始化工作向量和进程完成状态
    for (int i = 0; i < MAX_RESOURCES; i++) {
        work[i] = available[i];
    }
    for (int i = 0; i < MAX_PROCESSES; i++) {
        finish[i] = false;
    }

    // 执行银行家算法
    int count = 0;
    while (count < MAX_PROCESSES) {
        bool found = false;
        for (int i = 0; i < MAX_PROCESSES; i++) {
            if (finish[i] == false && is_safe(i)) {
                for (int j = 0; j < MAX_RESOURCES; j++) {
                    work[j] += allocation[i][j];
                }
                finish[i] = true;
                sequence[count++] = i;
                found = true;
                break;
            }
        }
        if (!found) {
            return false;
        }
    }
    *length = count;
    return true;
}

void schedule(int time_slice) {
    int sequence[MAX_PROCESSES];
    int length;
    bool is_safe_sequence = safe_sequence(sequence, &length);
    if (!is_safe_sequence) {
        printf("无法找到安全序列，进程会出现死锁！\n");
        return;
    }
    printf("安全序列为：");
    for (int i = 0; i < length; i++) {
        printf("P%d ", sequence[i] + 1);
    }
    printf("\n");

    int time = 0;
    int index = 0;
    while (index < length) {
        int process = sequence[index];
        int remaining_time = time_slice;
        while (remaining_time > 0 && need[process][0] > 0) {
            if (need[process][0] > remaining_time) {
                need[process][0] -= remaining_time;
                time += remaining_time;
                remaining_time = 0;
            } else {
                time += need[process][0];
                remaining_time -= need[process][0];
                need[process][0] = 0;
                allocation[process][0] += max[process][0];
            }
        }
        if (need[process][0] == 0) {
            printf("进程 P%d 完成时间片调度，释放资源！\n", process + 1);
            for (int i = 0; i < MAX_RESOURCES; i++) {
                available[i] += allocation[process][i];
                allocation[process][i] = 0;
            }
            index++;
        } else {
            printf("进程 P%d 暂停时间片调度，等待资源！\n", process + 1);
        }
    }

    printf("所有进程完成时间片调度！\n");
}

int main() {
    init();
    int time_slice;
    printf("请输入时间片长度：");
    scanf("%d", &time_slice);
    schedule(time_slice);
    return 0;
}

上述代码实现了以下功能：

1. 初始化资源可用数量、进程的资源分配和最大需求；
2. 判断是否存在安全序列（即是否会出现死锁）；
3. 调度进程，执行时间片轮转调度算法；
4. 释放资源，更新可用资源数量和进程的资源分配情况。

请注意，这只是一个简单的示例代码，可能还需要进行优化和改进。
