C++编写实现图书管理系统
C++编写的一个图书管理系统，供大家参考，具体内容如下
2018大一的课设，搬到这纪念一下，共1200多行代码
为图书管理人员编写一个图书管理系统，图书管理系统的设计主要是实现对图书的管理和相关操作，包括3个表：
图书信息表——存储图书的基本信息，包括书号、书名、作者、出版社、出版日期、存馆数量、定价等。
读者信息表——存储读者的基本信息，包括学号、姓名、学院、专业班级等。
图书借阅表——存储读者借书的相关信息，包括学号、姓名、书号、书名、借阅日期、应还日期、归还日期等。
用菜单选择方式完成了以下功能：
1、图书信息添加功能：包括书号、书名、作者、出版社、出版日期、存馆数量、定价等。
2、图书信息查询：分别按书名, 按作者名,
按出版单位等进行查询。
3、图书信息排序：按书号、书名等按升序进行排序。
4、图书信息的修改、删除：按书号或书名进行图书的修改和删除。
5、读者信息添加功能：包括学号、姓名、学院、专业、班级等。
6、读者信息查询：分别按学号、姓名、班级等进行查询。
7、读者信息排序：按学号、学院等按升序进行排序。
8、读者信息的修改、删除：按学号+姓名进行读者信息的修改和删除
9、图书借阅：输入学号+书号，如果该书图书信息表中的存馆数量大于0，则可以借出，借出相应数量后修改图书信息表中的存馆数量，在图书借阅表添加该同学的借阅。
10、图书归还：输入学号+书号，修改图书信息表中的存馆数量，在图书借阅表中记录该同学的归还时间。
11、图书借阅查询：分别按学号、书名、学院等进行查询。

C++实现图书管理系统课程设计
本文实例为大家分享了C++实现图书管理系统的具体代码,供大家参考,具体内容如下 大一 C++课设,没有用分文件的形式,只是把菜单页面单独分开了.用的是链表,都是一些基础的东西.另外采用了二维数组来保存读者借书信息,并将二维数组读入文件中. 功能: 1.首先是注册,登录,找回密码和修改密码功能,登录和注册使用了多态,并且登录页面采用了*符号加密.2.管理员在删除图书时,若用户此时已将此书借走,则会将此书从用户的借书书单中删去,实现了动态管理.3.容错率极高,每个页面都有返回上一页面的功能.4.每个
