使用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。

好的，这是一个比较典型的文件管理系统的设计题目，我可以给你提供一个大致的设计思路：

1.定义教室类，包括教室号、教学楼、类型、座位数、卫生责任人、设备责任人等属性。

2.设计教室管理类，实现教室信息的添加、修改、删除、查找等功能。

3.使用文件流将教室信息保存到硬盘中，可以选择使用文本文件或二进制文件。

4.设计主界面，提供友好的操作界面，方便用户进行各种操作。

5.设计教学楼类，包括教学楼的名称、楼层数、包含的教室等信息，实现显示某个教学楼所有教室的功能。

下面是一个可能的代码实现，仅供参考：

#include <vector>

上面的代码只是一个简单的示例，还有很多细节需要考虑，比如输入验证、错误处理、界面设计等，需要根据实际情况进行完善。
