用c++设计并实现一个教室管理系统，教室需设置不同的类型，系统可以实现对教室信息的添加，修改，删除，查找，预约等功能，教室信息需要以文件方式保存到计算机硬盘中，给出一个教学楼，可以显示该教学楼的所有教室。 基本功能： (1）教室要设置不同的类型，如多媒体教室、智慧教室等; (2）教室信息包括：房间号，教学楼、类型，座位数，卫生责任人，设备责任人等； (3）教室信息要保存在磁盘中; （4）系统界面应该尽量友好，方便使用。

以下是一个简单的教室管理系统的示例代码，实现了基本的添加、修改、删除、查找和预约功能，同时也将教室信息保存在磁盘中。

#include <iostream>

    int seats;  // 座位数
    string hygieneManager;  // 卫生责任人
    string equipmentManager;  // 设备责任人
    bool reserved;  // 是否被预约
};

// 定义教室管理系统类

    ClassroomManagementSystem() {
        LoadData();  // 从文件中读取教室信息
