设计一个c语言的火车订票系统的高级代码

好的，以下是一个简单的火车订票系统的C语言高级代码：

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

#define MAX_SEATS 100

struct Train {
    char name[50];
    int number;
    int seats[MAX_SEATS];
    int availableSeats;
};

struct Train trains[3] = {
    {"Express", 12345, {0}, MAX_SEATS},
    {"Superfast", 67890, {0}, MAX_SEATS},
    {"Local", 24680, {0}, MAX_SEATS}
};

void displayMenu() {
    printf("************ Train Booking System ************\n");
    printf("1. Book a ticket\n");
    printf("2. Cancel a ticket\n");
    printf("3. Display train details\n");
    printf("4. Exit\n");
    printf("***********************************************\n");
}

void bookTicket(int trainIndex) {
    int seatNo;
    bool isSeatAvailable = false;

    for(int i=0; i<MAX_SEATS; i++) {
        if(trains[trainIndex].seats[i] == 0) {
            isSeatAvailable = true;
            seatNo = i+1;
            break;
        }
    }

    if(isSeatAvailable) {
        printf("Your seat has been booked. Seat number: %d\n", seatNo);
        trains[trainIndex].seats[seatNo-1] = 1;
        trains[trainIndex].availableSeats--;
    } else {
        printf("Sorry, no seats available.\n");
    }
}

void cancelTicket(int trainIndex) {
    int seatNo;
    printf("Enter the seat number to cancel: ");
    scanf("%d", &seatNo);

    if(trains[trainIndex].seats[seatNo-1] == 1) {
        printf("Your ticket has been cancelled. Seat number: %d\n", seatNo);
        trains[trainIndex].seats[seatNo-1] = 0;
        trains[trainIndex].availableSeats++;
    } else {
        printf("Invalid seat number.\n");
    }
}

void displayTrainDetails(int trainIndex) {
    printf("Train Name: %s\n", trains[trainIndex].name);
    printf("Train Number: %d\n", trains[trainIndex].number);
    printf("Total seats: %d\n", MAX_SEATS);
    printf("Available seats: %d\n", trains[trainIndex].availableSeats);
}

int main() {
    int choice, trainIndex;
    bool isQuit = false;

    while(!isQuit) {
        displayMenu();
        printf("Enter your choice: ");
        scanf("%d", &choice);

        switch(choice) {
            case 1:
                printf("Enter the train number (1-3): ");
                scanf("%d", &trainIndex);
                bookTicket(trainIndex-1);
                break;
            case 2:
                printf("Enter the train number (1-3): ");
                scanf("%d", &trainIndex);
                cancelTicket(trainIndex-1);
                break;
            case 3:
                printf("Enter the train number (1-3): ");
                scanf("%d", &trainIndex);
                displayTrainDetails(trainIndex-1);
                break;
            case 4:
                isQuit = true;
                break;
            default:
                printf("Invalid choice.\n");
                break;
        }
    }

    return 0;
}

这个火车订票系统可以让用户选择预订、取消预订或查看火车详情。火车的座位数是固定的，每个座位都可以预订或取消预订。当一张车票被预订或取消预订时，系统会自动更新可用座位的数量。
