C++图书管理
工藤学编程 人气:0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!
