C++实现简单图书馆管理系统 C++实现简单图书馆管理系统

本文实例为大家分享了C++实现简单图书馆管理系统的具体代码，供大家参考，具体内容如下
写了一个小项目，图书馆系统，功能如下：
1，添加书籍
2，删除书籍（可删除还没外借的书籍）
3，读者借书
4，读者还书
5，按书籍登入号查看信息（每一本书的书籍登入号唯一，如有5本相同书名作者的书，那就有5个不同的书籍登入号）
6，查询所有图书信息（可以直接查看到同本书在图书馆中的剩余和借出情况）
7，查看指定读者的借书详情
8，注册新读者
9，查看所有书籍信息（可以详细到每个登入号和此登入号书籍的借阅情况：如谁借的，借阅日期）
采用客户端和服务器模式，服务器端接收客户端，一旦接收到便启用线程，然后相应来自此客户端的不同请求
