C++图书管理系统程序源代码 C++图书管理系统程序源代码

本文实例为大家分享了C++图书管理系统程序的具体代码，供大家参考，具体内容如下
大一期末c++综合实验，功能基本都实现了，但是代码写的有些繁琐，还有很大的优化空间，仅供参考。
实验要求实验目的：
1、能够综合运用面向对象程序设计方法，设计实现一个相对完整信息管理应用程序。
2、能够适当进行题目分析、实验设计、核心代码描述、实验结果分析等。
实验：设计并编写一个C++风格应用程序，模拟一个图书管理系统应用程序，支持系统用户的图书借阅、图书管理、用户管理等功能。图书借阅管理主要包括图书借阅、图书归还、借阅信息查看等功能。图书管理主要包括图书的增加、删除、修改、查看、统计等功能。用户管理主要包括用户注册、登录、修改密码、修改个人信息、设置用户类型等功能。
具体要求： 1、定义图书管理系统中的Book书目类（还可以定义User用户类、Log图书借还日志类等）。
2、合理应用类的继承性进行馆藏资源的继承性定义，可分为书、碟片、电子资源等（或将系统用户分为读者、图书管理员、系统管理员）。
3、根据不同类型用户，登录系统显示不同的用户功能菜单，实现不同的操作处理，如学生与教师所借阅书的数量和天数均不相同（或考虑图书馆中多种馆藏资源支持的用户操作有所区别）。
4、增加异常处理，在借阅图书时，已到所能借阅图书数量的最大数量给予提示；归还图书时，图书已超期需要缴纳罚款。
5、通过重载运算符“<<”和“>>”方便图书信息、读者信息录入等操作，并实现将馆藏图书信息、借阅记录等保存到磁盘，形成图书借还日志文件。
6、扩展实验：可尝试使用MFC可视化界面提高用户操作方便性和友好性。
