图书馆座位管理系统c语言

以下是一个简单的C语言图书馆座位管理系统的示例：

#include <stdio.h>

#define MAX_SEATS 100

// 座位状态
typedef enum {
    EMPTY,
    OCCUPIED
} SeatStatus;

// 座位结构体
typedef struct {
    int seatNumber;
    SeatStatus status;
    char occupantName[50];
} Seat;

// 初始化座位
void initializeSeats(Seat seats[], int numSeats) {
    for (int i = 0; i < numSeats; i++) {
        seats[i].seatNumber = i + 1;
        seats[i].status = EMPTY;
    }
}

// 显示座位状态
void displaySeatStatus(Seat seats[], int numSeats) {
    printf("座位状态:\n");
    for (int i = 0; i < numSeats; i++) {
        printf("座位号: %d\t状态: %s\t占用者姓名: %s\n", seats[i].seatNumber, seats[i].status == EMPTY ? "空闲" : "已占用", seats[i].occupantName);
    }
}

// 预定座位
void reserveSeat(Seat seats[], int numSeats) {
    int seatNumber;
    char occupantName[50];

    printf("请输入要预定的座位号: ");
    scanf("%d", &seatNumber);

    if (seatNumber < 1 || seatNumber > numSeats) {
        printf("无效的座位号！\n");
        return;
    }

    if (seats[seatNumber - 1].status == OCCUPIED) {
        printf("该座位已被占用！\n");
        return;
    }

    printf("请输入占用者姓名: ");
    scanf("%s", occupantName);

    seats[seatNumber - 1].status = OCCUPIED;
    strcpy(seats[seatNumber - 1].occupantName, occupantName);

    printf("座位预定成功！\n");
}

// 释放座位
void releaseSeat(Seat seats[], int numSeats) {
    int seatNumber;

    printf("请输入要释放的座位号: ");
    scanf("%d", &seatNumber);

    if (seatNumber < 1 || seatNumber > numSeats) {
        printf("无效的座位号！\n");
        return;
    }

    if (seats[seatNumber - 1].status == EMPTY) {
        printf("该座位已是空闲状态！\n");
        return;
    }

    seats[seatNumber - 1].status = EMPTY;
    strcpy(seats[seatNumber - 1].occupantName, "");

    printf("座位释放成功！\n");
}

int main() {
    Seat seats[MAX_SEATS];
    int numSeats;

    printf("请输入座位数量: ");
    scanf("%d", &numSeats);

    initializeSeats(seats, numSeats);

    int choice;
    do {
        printf("\n图书馆座位管理系统菜单:\n");
        printf("1. 显示座位状态\n");
        printf("2. 预定座位\n");
        printf("3. 释放座位\n");
        printf("0. 退出\n");
        printf("请输入选项: ");
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                displaySeatStatus(seats, numSeats);
                break;

                break;
            case 0:
                printf("感谢使用图书馆座位管理系统！\n");
                break;
            default:
