用c语言设计并实现一个银行窗口排队管理系统，模拟用户排队、办理业务结束后 离队等过程。具体要求如下： 1.窗口配置及状态管理 窗口应有编号、业务类型、排队队列、工作人员编号（唯一）等属 性； 窗口数量无限制；

下面是一个简单的银行窗口排队管理系统的实现，包括窗口、顾客和队列三个类：

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

#define MAX_WINDOW_NUM 10
#define MAX_QUEUE_LENGTH 100

// 窗口状态
enum WindowStatus {
    IDLE,
    BUSY,
    PAUSED
};

// 业务类型
enum ServiceType {
    SERVICE_A,
    SERVICE_B,
    SERVICE_C
};

// 顾客
struct Customer {
    int number; // 顾客编号
    enum ServiceType service_type; // 顾客需要办理的业务类型
    time_t enter_time; // 顾客进入队列的时间
    time_t start_time; // 顾客开始服务的时间
    time_t end_time; // 顾客完成服务的时间
};

// 队列
struct Queue {
    int front; // 队头
    int rear; // 队尾
    struct Customer *customers; // 顾客数组
};

// 窗口
struct Window {
    int number; // 窗口编号
    enum ServiceType service_type; // 窗口可以处理的业务类型
    struct Queue queue; // 窗口前的队列
    enum WindowStatus status; // 窗口状态
    int worker_number; // 工作人员编号
};

// 初始化队列
void init_queue(struct Queue *queue) {
    queue->front = queue->rear = 0;
    queue->customers = (struct Customer *)malloc(sizeof(struct Customer) * MAX_QUEUE_LENGTH);
}

// 判断队列是否为空
int is_queue_empty(const struct Queue *queue) {
    return queue->front == queue->rear;
}

// 判断队列是否已满
int is_queue_full(const struct Queue *queue) {
    return (queue->rear + 1) % MAX_QUEUE_LENGTH == queue->front;
}

// 添加顾客到队列
void enqueue(struct Queue *queue, const struct Customer *customer) {
    if (is_queue_full(queue)) {
        printf("Error: queue is full!\n");
        return;
    }
    queue->customers[queue->rear] = *customer;
    queue->rear = (queue->rear + 1) % MAX_QUEUE_LENGTH;
}

// 从队列中取出顾客
struct Customer dequeue(struct Queue *queue) {
    if (is_queue_empty(queue)) {
        printf("Error: queue is empty!\n");
        exit(1);
    }
    struct Customer customer = queue->customers[queue->front];
    queue->front = (queue->front + 1) % MAX_QUEUE_LENGTH;
    return customer;
}

// 初始化窗口
void init_window(struct Window *window, int number, enum ServiceType service_type, int worker_number) {
    window->number = number;
    window->service_type = service_type;
    init_queue(&(window->queue));
    window->status = IDLE;
    window->worker_number = worker_number;
}

// 判断窗口是否空闲
int is_window_idle(const struct Window *window) {
    return window->status == IDLE;
}

// 判断窗口是否正在服务中
int is_window_busy(const struct Window *window) {
    return window->status == BUSY;
}

// 判断窗口是否已暂停服务
int is_window_paused(const struct Window *window) {
    return window->status == PAUSED;
}

// 将窗口状态设置为空闲
void set_window_idle(struct Window *window) {
    window->status = IDLE;
}

// 将窗口状态设置为正在服务
void set_window_busy(struct Window *window) {
    window->status = BUSY;
}

// 将窗口状态设置为暂停服务
void set_window_paused(struct Window *window) {
    window->status = PAUSED;
}

// 将顾客加入窗口前的队列
void add_customer_to_window_queue(struct Window *window, const struct Customer *customer) {
    enqueue(&(window->queue), customer);
}

// 开始服务第一个顾客
void start_service(struct Window *window) {
    if (is_window_busy(window) || is_queue_empty(&(window->queue))) {
        return;
    }
    struct Customer customer = dequeue(&(window->queue));
    customer.start_time = time(NULL);
    set_window_busy(window);
    printf("窗口 %d 开始为顾客 %d 办理业务\n", window->number, customer.number);
}

// 完成服务
void finish_service(struct Window *window) {
    if (is_window_idle(window)) {
        return;
    }
    set_window_idle(window);
    printf("窗口 %d 完成业务\n", window->number);
}

// 处理顾客
void process_customer(struct Window *window, struct Customer *customer) {
    add_customer_to_window_queue(window, customer);
    if (is_window_idle(window)) {
        start_service(window);
    }
}

// 主函数
int main() {
    // 初始化窗口
    struct Window windows[MAX_WINDOW_NUM];
    for (int i = 0; i < MAX_WINDOW_NUM; i++) {
        init_window(&(windows[i]), i + 1, SERVICE_A, i + 1);
    }

    // 模拟顾客到来
    struct Customer customer1 = {.number = 1, .service_type = SERVICE_A, .enter_time = time(NULL)};
    process_customer(&(windows[0]), &customer1);

    struct Customer customer2 = {.number = 2, .service_type = SERVICE_B, .enter_time = time(NULL)};
    process_customer(&(windows[1]), &customer2);

    struct Customer customer3 = {.number = 3, .service_type = SERVICE_C, .enter_time = time(NULL)};
    process_customer(&(windows[2]), &customer3);

    // 模拟服务
    sleep(5);
    finish_service(&(windows[0]));

    sleep(3);
    finish_service(&(windows[1]));
    start_service(&(windows[1]));

    sleep(4);
    finish_service(&(windows[1]));

    sleep(2);
    finish_service(&(windows[2]));

    return 0;
}

这个实现只是一个简单的示例，可以根据实际需求进行扩展和改进。
