C++实现图书管理系统课程设计(面向对象) C++实现图书管理系统课程设计

本文实例为大家分享了C++实现图书管理系统课程设计，供大家参考，具体内容如下
1.题目：【1】：工作人员登录后，可以进行的操作
添加学生的信息（学号，姓名，院系，最大借阅的图书数量等）；
修改学生的信息（学号，姓名，院系，最大借阅的图书数量等）；
删除学生的信息（学号，姓名，院系，最大借阅的图书数量等）；
如果某个学生退学，就要清除他的信息；
查看学生的信息；
添加图书的信息（图书号，书名，作者，出版社，数量等）；
修改图书的信息（图书号，书名，作者，出版社，数量等）；
删除图书的信息（图书号，书名，作者，出版社，数量等）；
查看图书的信息；
【2】：学生登录后，可以进行的操作
查看学生自己借阅的数目信息；
借阅图书；
归还图书；
备注：要求将学生和图书信息存放到外存上，每次从外存读取数据；
