C++编写的一个图书管理系统

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：

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。
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。
图书信息排序：按书号、书名等按升序进行排序。
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。
读者信息添加功能：包括学号、姓名、学院、专业、班级等。
读者信息查询：分别按学号、姓名、班级等进行查询。
读者信息排序：按学号、学院等按升序进行排序。
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
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。
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。
图书借阅查询：分别按学号、书名、学院等进行查询。
