飞机订票系统 c语言代码

以下是一个简单的飞机订票系统的C语言代码示例：

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

#define MAX_SEATS 100

struct Seat {
    int seat_num;
    char passenger_name[30];
    int is_booked;
};

struct Seat seats[MAX_SEATS];

void print_menu() {
    printf("\n\n");
    printf("Airline Ticket Booking System\n");
    printf("----------------------------\n");
    printf("1. View available seats\n");
    printf("2. Book a seat\n");
    printf("3. Cancel a booking\n");
    printf("4. Exit\n");
}

void view_seats() {
    printf("Available seats:\n");
    for (int i = 0; i < MAX_SEATS; i++) {
        if (!seats[i].is_booked) {
            printf("Seat %d: Available\n", seats[i].seat_num);
        }
    }
}

void book_seat() {
    int seat_num;
    printf("Enter seat number to book: ");
    scanf("%d", &seat_num);

    if (seats[seat_num-1].is_booked) {
        printf("Seat %d is already booked.\n", seat_num);
        return;
    }

    char name[30];
    printf("Enter passenger name: ");
    scanf("%s", name);

    seats[seat_num-1].seat_num = seat_num;
    strcpy(seats[seat_num-1].passenger_name, name);
    seats[seat_num-1].is_booked = 1;

    printf("Seat %d successfully booked for %s.\n", seat_num, name);
}

void cancel_booking() {
    int seat_num;
    printf("Enter seat number to cancel booking: ");
    scanf("%d", &seat_num);

    if (!seats[seat_num-1].is_booked) {
        printf("Seat %d is not booked.\n", seat_num);
        return;
    }

    seats[seat_num-1].is_booked = 0;
    printf("Booking for seat %d cancelled.\n", seat_num);
}

int main() {
    for (int i = 0; i < MAX_SEATS; i++) {
        seats[i].seat_num = i+1;
        seats[i].is_booked = 0;
    }

    int choice;
    do {
        print_menu();
        printf("Enter your choice: ");
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                view_seats();
                break;
            case 2:
                book_seat();
                break;
            case 3:
                cancel_booking();
                break;
            case 4:
                printf("Exiting program.\n");
                return 0;
            default:
                printf("Invalid choice.\n");
        }
    } while (1);

    return 0;
}

这个系统可以显示可用座位，预订座位和取消预订，并使用结构体来表示座位信息。请注意，这只是一个简单的示例，并且可能需要进行更多的错误检查和输入验证。
