课程设计目的
作为软件工程和计算机科学与技术专业的基本课程，课程设计不仅涵盖了C++语言的知识体系，又与工程的实际需要切实相关。通过课程设计的综合性训练，对开发者解决实际问题能力，编程能力，动手能力有很大的提升，更有助于样成良好的编程习惯
图书管理系统需求分析
某高校为更好的管理图书馆，现需设计一简易图书管理系统，实现新书录入，图书资料查询，显示总图书信息功能。要求开发的系统需要具备以下功能：
1.实现读者借阅图书；
2.实现读者归还图书；
3.实现对图书信息的综合管理： （设置二级子目录实现信息的增，删，改，查等操作）
4.实现对读者信息的综合管理： （设置二级子目录实现信息的增，删，改，查等操作）
5.显示用户信息：显示所有用户信息，含学号、姓名、借阅状况等信息；
6.返回主界面；
设计实现
本部分设计内容包括：类的设计、数据成员设计、成员函数设计，以及主程序设计（模块函数实现，主函数） 【源码中详细解释，此处不作赘述】
