C++ を使用して単純なフライト クエリ システムを実装するにはどうすればよいですか?

struct Flight {
    string flightNumber;
    string departureTime;
    string arrivalTime;
    string airline;
};

const int MAX_FLIGHTS = 100;
Flight flights[MAX_FLIGHTS];

void addFlight() {
    string flightNumber;
    string departureTime;
    string arrivalTime;
    string airline;
    
    // 获取用户输入的航班信息
    cout << "请输入航班号：";
    cin >> flightNumber;
    cout << "请输入出发时间：";
    cin >> departureTime;
    cout << "请输入到达时间：";
    cin >> arrivalTime;
    cout << "请输入航班公司：";
    cin >> airline;
    
    // 创建一个新的航班对象
    Flight newFlight;
    newFlight.flightNumber = flightNumber;
    newFlight.departureTime = departureTime;
    newFlight.arrivalTime = arrivalTime;
    newFlight.airline = airline;
    
    // 将航班对象添加到航班数组中
    for (int i = 0; i < MAX_FLIGHTS; i++) {
        if (flights[i].flightNumber.empty()) {
            flights[i] = newFlight;
            cout << "航班添加成功！" << endl;
            return;
        }
    }
    
    cout << "航班列表已满，无法添加新的航班！" << endl;
}

void searchFlight() {
    string flightNumber;
    
    // 获取用户输入的航班号
    cout << "请输入要查询的航班号：";
    cin >> flightNumber;
    
    // 查询航班信息
    for (int i = 0; i < MAX_FLIGHTS; i++) {
        if (flights[i].flightNumber == flightNumber) {
            cout << "航班号：" << flights[i].flightNumber << endl;
            cout << "出发时间：" << flights[i].departureTime << endl;
            cout << "到达时间：" << flights[i].arrivalTime << endl;

            return;
        }
    }

}

    while (true) {
        int choice;
        
        // 显示菜单选项
        cout << "航班查询系统" << endl;
        cout << "1. 添加航班" << endl;
        cout << "2. 查询航班" << endl;
        cout << "3. 退出系统" << endl;
        cout << "请选择操作：";
        cin >> choice;
        
        // 根据用户选择执行相应的操作
        switch (choice) {
            case 1:
                addFlight();
                break;
            case 2:
                searchFlight();
                break;
            case 3:
