用C++代码写一个火车票管理系统

以下是一个简单的火车票管理系统的 C++ 代码，实现了添加、删除、查询和展示火车票信息的功能。

#include <iostream>
#include <string>
#include <vector>

using namespace std;

// 火车票信息结构体
struct Ticket {
    string trainNumber;  // 车次
    string startStation; // 起始站
    string endStation;   // 终点站
    string departureTime;   // 出发时间
    string arrivalTime; // 到达时间
    int price;  // 票价
};

// 火车票管理系统类
class TicketSystem {
private:
    vector<Ticket> tickets; // 火车票信息容器

public:
    // 添加一张火车票
    void addTicket(const Ticket& ticket) {
        tickets.push_back(ticket);
        cout << "添加火车票成功！" << endl;
    }

    // 删除一张火车票
    void deleteTicket(const string& trainNumber) {
        for (auto it = tickets.begin(); it != tickets.end(); ++it) {
            if (it->trainNumber == trainNumber) {
                tickets.erase(it);
                cout << "删除火车票成功！" << endl;
                return;
            }
        }
        cout << "没有找到该车次的火车票。" << endl;
    }

    // 查询一张火车票
    void queryTicket(const string& trainNumber) {
        for (auto it = tickets.begin(); it != tickets.end(); ++it) {
            if (it->trainNumber == trainNumber) {
                cout << "车次：" << it->trainNumber << endl;
                cout << "起始站：" << it->startStation << endl;
                cout << "终点站：" << it->endStation << endl;
                cout << "出发时间：" << it->departureTime << endl;
                cout << "到达时间：" << it->arrivalTime << endl;
                cout << "票价：" << it->price << endl;
                return;
            }
        }
        cout << "没有找到该车次的火车票。" << endl;
    }

    // 显示所有火车票信息
    void showAllTickets() {
        for (auto it = tickets.begin(); it != tickets.end(); ++it) {
            cout << "车次：" << it->trainNumber << endl;
            cout << "起始站：" << it->startStation << endl;
            cout << "终点站：" << it->endStation << endl;
            cout << "出发时间：" << it->departureTime << endl;
            cout << "到达时间：" << it->arrivalTime << endl;
            cout << "票价：" << it->price << endl;
            cout << endl;
        }
    }
};
