用C语言写一个用队列实现的银行模拟取钱代码

好的，以下是用C语言写一个用队列实现的银行模拟取钱代码的示例：

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

#define MAX_QUEUE_SIZE 100

typedef struct {
    int id;
    int amount;
} Customer;

typedef struct {
    Customer data[MAX_QUEUE_SIZE];
    int front;
    int rear;
} Queue;

void initQueue(Queue *q) {
    q->front = q->rear = 0;
}

int isQueueEmpty(Queue *q) {
    return q->front == q->rear;
}

int isQueueFull(Queue *q) {
    return (q->rear + 1) % MAX_QUEUE_SIZE == q->front;
}

void enqueue(Queue *q, Customer c) {
    if (isQueueFull(q)) {
        printf("Queue is full!\n");
        exit(1);
    }
    q->data[q->rear] = c;
    q->rear = (q->rear + 1) % MAX_QUEUE_SIZE;
}

Customer dequeue(Queue *q) {
    if (isQueueEmpty(q)) {
        printf("Queue is empty!\n");
        exit(1);
    }
    Customer c = q->data[q->front];
    q->front = (q->front + 1) % MAX_QUEUE_SIZE;
    return c;
}

int main() {
    Queue q;
    initQueue(&q);

    int n;
    printf("Enter the number of customers: ");
    scanf("%d", &n);

    for (int i = 1; i <= n; i++) {
        Customer c;
        c.id = i;
        printf("Enter the amount of money for customer %d: ", i);
        scanf("%d", &c.amount);
        enqueue(&q, c);
    }

    int total = 0;
    while (!isQueueEmpty(&q)) {
        Customer c = dequeue(&q);
        printf("Customer %d withdraws %d yuan.\n", c.id, c.amount);
        total += c.amount;
    }

    printf("Total amount of money withdrawn: %d yuan.\n", total);

    return 0;
}

这个程序使用队列来模拟银行的取款过程。首先，用户需要输入要模拟的客户数量，然后输入每个客户要取款的金额。程序将每个客户的信息存储在队列中，然后按照队列的顺序处理每个客户，输出客户的编号和取款金额，并计算所有客户取款的总金额。
