c语言银行排队系统带有vip功能代码

在编写C语言的银行排队系统并添加VIP功能时，我们需要创建几个主要的结构体来表示客户、普通队列和VIP队列，并定义函数来处理客户的加入、离开和服务顺序。由于这是一个复杂的示例，我将提供一个简化的伪代码框架，你可以根据需要进行扩展：

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

typedef struct Customer {
    int id;
    char priority; // 'P' for regular, 'V' for VIP
} Customer;

typedef struct QueueNode {
    Customer customer;
    struct QueueNode *next;
} QueueNode;

// Regular queue
QueueNode *regular_queue;
int regular_size;

// VIP queue
QueueNode *vip_queue;
int vip_size;

// Function to enqueue a customer (enqueue at the end)
void enqueue(Customer *customer, QueueNode **queue) {
    QueueNode *new_node = (QueueNode*)malloc(sizeof(QueueNode));
    new_node->customer = *customer;
    new_node->next = NULL;
    
    if (*queue == NULL) {
        *queue = new_node;
    } else {
        QueueNode *temp = *queue;
        while (temp->next != NULL) temp = temp->next;
        temp->next = new_node;
    }
}

// Function to check and serve customers based on priority
void serveCustomers() {
    if (regular_queue && vip_queue) {
        if (regular_size > 0 && vip_size == 0) {
            QueueNode *current = regular_queue;
            while (current != NULL) {
                printf("Serving %d - Priority: %c\n", current->customer.id, current->customer.priority);
                // Service logic here
                current = current->next;
                regular_size--;
            }
        } else if (vip_size > 0) {
            QueueNode *current = vip_queue;
            while (current != NULL) {
                printf("Serving %d - Priority: %c\n", current->customer.id, current->customer.priority);
                // Service logic here
                current = current->next;
                vip_size--;
            }
        }
    }
}

int main() {
    // Initialize queues
    regular_queue = NULL;
    regular_size = 0;
    vip_queue = NULL;
    vip_size = 0;
    
    // Example usage
    Customer regular = {1, 'P'};
    Customer vip = {2, 'V'};
    enqueue(&regular, &regular_queue); // Enqueue regular
    enqueue(&vip, &vip_queue); // Enqueue VIP

    // Serve customers
    serveCustomers();

    return 0;
}
