用c语言完成电影院的售票管理系统代码

以下是使用C语言实现的电影院售票管理系统代码示例：

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

#define MAX_SEATS 20 // 最大座位数

// 电影信息结构体
typedef struct {
    char name[50]; // 电影名称
    int duration; // 电影时长（分钟）
} Movie;

// 座位信息结构体
typedef struct {
    int seat_number; // 座位号
    int is_booked; // 是否已售出
    char customer_name[50]; // 顾客姓名
} Seat;

// 初始化座位信息
void init_seats(Seat seats[]) {
    for (int i = 0; i < MAX_SEATS; i++) {
        seats[i].seat_number = i + 1;
        seats[i].is_booked = 0;
        strcpy(seats[i].customer_name, "");
    }
}

// 显示座位信息
void display_seats(Seat seats[]) {
    printf("座位信息：\n");
    printf("座位号\t是否已售出\t顾客姓名\n");
    for (int i = 0; i < MAX_SEATS; i++) {
        printf("%d\t%s\t\t%s\n", seats[i].seat_number, seats[i].is_booked ? "是" : "否", seats[i].customer_name);
    }
}

// 选择电影
Movie select_movie() {
    Movie movie1 = {"复仇者联盟4", 181};
    Movie movie2 = {"头号玩家", 140};
    Movie movie3 = {"寻梦环游记", 105};

    printf("请选择电影：\n");
    printf("1. %s（%d分钟）\n", movie1.name, movie1.duration);
    printf("2. %s（%d分钟）\n", movie2.name, movie2.duration);
    printf("3. %s（%d分钟）\n", movie3.name, movie3.duration);

    int choice;
    do {
        printf("请输入您的选择（1-3）：");
        scanf("%d", &choice);
    } while (choice < 1 || choice > 3);

    switch (choice) {
        case 1:
            return movie1;
        case 2:
            return movie2;
        case 3:
            return movie3;
        default:
            break;
    }

    return movie1; // 默认返回第一部电影
}

// 选择座位
int select_seat(Seat seats[]) {
    int seat_number;
    do {
        printf("请输入座位号（1-%d）：", MAX_SEATS);
        scanf("%d", &seat_number);
    } while (seat_number < 1 || seat_number > MAX_SEATS);

    Seat *seat = &seats[seat_number - 1];
    if (seat->is_booked) {
        printf("该座位已售出，请选择其他座位！\n");
        return -1;
    }

    return seat_number;
}

// 购票
void book_ticket(Seat seats[], Movie movie) {
    int seat_number = select_seat(seats);
    if (seat_number == -1) {
        return;
    }

    Seat *seat = &seats[seat_number - 1];

    char customer_name[50];
    printf("请输入您的姓名：");
    scanf("%s", customer_name);

    seat->is_booked = 1;
    strcpy(seat->customer_name, customer_name);

    printf("恭喜您，购票成功！\n");
    printf("您已成功购买 %s 的电影票，座位号为 %d，电影时长为 %d 分钟。\n", movie.name, seat_number, movie.duration);
}

// 退票
void return_ticket(Seat seats[]) {
    int seat_number = select_seat(seats);
    if (seat_number == -1) {
        return;
    }

    Seat *seat = &seats[seat_number - 1];

    seat->is_booked = 0;
    strcpy(seat->customer_name, "");

    printf("退票成功！\n");
}

int main() {
    Movie movie = select_movie(); // 选择电影

    Seat seats[MAX_SEATS]; // 初始化座位信息
    init_seats(seats);

    int choice;
    do {
        printf("\n");
        printf("请选择操作：\n");
        printf("1. 显示座位信息\n");
        printf("2. 购票\n");
        printf("3. 退票\n");
        printf("4. 退出系统\n");

        scanf("%d", &choice);

        switch (choice) {
            case 1:
                display_seats(seats);
                break;
            case 2:
                book_ticket(seats, movie);
                break;
            case 3:
                return_ticket(seats);
                break;
            default:
                break;
        }
    } while (choice != 4);

    return 0;
}

这个代码实现了基本的售票管理系统功能，包括选择电影、选择座位、购票、退票等操作。可以根据自己的需求进行修改和扩展。
