用C加加写一个火车票售票系统

以下是一个简单的火车票售票系统的实现，包括车票信息的输入和查询功能：

#include <iostream>
#include <string>
using namespace std;

struct Ticket {
    string trainNumber;     // 车次
    string startStation;    // 起点站
    string endStation;      // 终点站
    string departureTime;   // 出发时间
    int seatCount;          // 座位数
    int soldCount;          // 已售座位数
};

int main() {
    Ticket tickets[100];    // 最多存储100个车票信息
    int ticketCount = 0;    // 当前车票数量
    int choice;             // 用户选择的操作

    while (true) {
        cout << "请选择操作：\n";
        cout << "1. 添加车票信息\n";
        cout << "2. 查询车票信息\n";
        cout << "3. 退出程序\n";
        cout << "请选择：";
        cin >> choice;

        if (choice == 1) {  // 添加车票信息
            if (ticketCount >= 100) {
                cout << "车票信息已满，无法继续添加！\n";
            } else {
                Ticket ticket;
                cout << "请输入车次：";
                cin >> ticket.trainNumber;
                cout << "请输入起点站：";
                cin >> ticket.startStation;
                cout << "请输入终点站：";
                cin >> ticket.endStation;
                cout << "请输入出发时间：";
                cin >> ticket.departureTime;
                cout << "请输入座位数：";
                cin >> ticket.seatCount;
                ticket.soldCount = 0;
                tickets[ticketCount] = ticket;
                ticketCount++;
                cout << "车票信息添加成功！\n";
            }
        } else if (choice == 2) {  // 查询车票信息
            string trainNumber;
            cout << "请输入要查询的车次：";
            cin >> trainNumber;

            bool found = false;
            for (int i = 0; i < ticketCount; i++) {
                if (tickets[i].trainNumber == trainNumber) {
                    cout << "车次：" << tickets[i].trainNumber << endl;
                    cout << "起点站：" << tickets[i].startStation << endl;
                    cout << "终点站：" << tickets[i].endStation << endl;
                    cout << "出发时间：" << tickets[i].departureTime << endl;
                    cout << "座位数：" << tickets[i].seatCount << endl;
                    cout << "已售座位数：" << tickets[i].soldCount << endl;
                    found = true;
                    break;
                }
            }

            if (!found) {
                cout << "未找到车次为" << trainNumber << "的车票信息！\n";
            }
        } else if (choice == 3) {  // 退出程序
            cout << "程序已退出！\n";
            break;
        } else {
            cout << "无效的选择，请重新输入！\n";
        }
    }

    return 0;
}

以上代码仅作为示例，实际的火车票售票系统需要考虑更多的功能和细节，如票价计算、座位选择、支付等功能。
