图书管理系统功能概览：
- 登录，注册
- 学生,老师借书，查看自己当前借书情况，还书。
- 管理员增加书，查看当前借阅情况，查看当前所有借阅人，图书信息。
代码概览：
各个模块主要负责功能
COperationManagement.h 负责登录，注册，管理员，将图书，初始化操作，将借阅信息等从文件中读取出来，放入容器中，便于操作，不用一直对文件进行I/O.
CBook.h 用于对书抽象，并实现了>>的重载，便于文件读入，读出
CUser.h 工具人，作为老师，学生的父类
CStudent.h 对学生进行的抽象
CTeacher.h 对老师进行的抽象
CAdministrator.h 对管理的抽象
CManagementBooks.h 用户所有的相关操作的中间执行者，有设计模式中代理的思想
源.cpp 界面的的实现与系统入口
说明：业务代码在2023/11/14日后不完全开源，需要完整代码可私聊我，可以私聊我发你完整代码，还有就是文件读入建议大家都直接放在相应项目里面，不然就写绝对路径。有问题欢迎大家在评论区提问，喜欢就点个赞咯！
