功能
会议室管理：
- 添加会议室：设置ID、名称、容量和是否有投影仪
- 删除会议室：根据ID删除会议室
预约管理：
- 预约会议室：选择会议室、预约人和时间
- 取消预约：取消已有的预约记录
- 查询会议室状态：查看特定会议室的详细信息
查询功能：
- 显示所有会议室：列出系统中所有会议室
- 查找可用会议室：根据时间、容量和投影仪需求查找可用会议室
数据持久化：
- 保存数据：将会议室和预约信息保存到文件
- 加载数据：从文件加载之前保存的数据
编译和运行
将代码保存为
meeting_room_system.cpp使用C++编译器编译：
g++ -std=c++11 meeting_room_system.cpp -o meeting_room_system运行程序：
./meeting_room_system

扩展建议
- 用户认证：添加用户登录和权限管理功能
- 图形界面：使用Qt等框架开发图形用户界面
- 网络功能：添加网络支持，实现远程预约
- 邮件通知：预约成功或取消时发送邮件通知
- 数据库支持：使用SQLite或MySQL替代文件存储
- 日历集成：与Google Calendar或Outlook集成
