C++详细实现完整图书管理功能-C/C++开发

随着网络技术的高速发展，计算机应用的普及，利用计算机对图书馆的日常工作进行管理势在必行，本篇文章涵盖一个图书管理系统的全部实现代码,大家可以查缺补漏，提升水平

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：代码100%完整，如果大家不想CV，也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！

	cout << "1.学生最多共可借三本书,老师最多共可借五本"<<endl<<endl;
	cout << "请选择您的登录方式 1:老师 2:学生 3:管理员" << endl;
	int t;
	cin >> t;
	if (t == 1)

	}
	else if(t == 2)
