C++详细实现完整图书管理功能

第C++详细实现完整图书管理功能目录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：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！

全部代码与讲解:

1.源.cpp

#includeiostream

#include"CBook.h"

#include"CStudent.h"

#include"CManagementBooks.h"

#include"CTeacher.h"

#includefstream

#include"CAdministrator.h"

#include"COperationManagement.h"

usingnamespacestd;

intmain()

CUser*user=nullptr;

COperationManagementom;

om.init(mb);

cout"*****欢迎来到图书馆*****"endl;

cout"注意事项"endl;

cout"1.学生最多共可借三本书,老师最多共可借五本"endlendl;

cout"请选择您的登录方式1:老师2:学生3:管理员"endl;
