项目描述：

（本次项目呢时用C++的知识点，来实现的，主要使用类，静态成员函数，成员变量，定义一个基类来展开的。（写的不好请多多指教）

1、图书有电子书和纸质书两种

2、图书按照类别存放在不同的书架

3、图书管理员按照书的类别对书进行操作

实现功能：

1、图书管理员将图书按照类别放入书架

2、图书管理员将某本书从书架中删除

3、图书管理员查找某本书的信息或者所有书的信息

4、图书管理员修改某本书的信息

5、图书管理员浏览某本书的内容

项目的类：

  1、纸质书类：

       （1） 成员变量：书名  作者   价格  类别   编号   数量（书的数量，所有书的对象都能知

       （2） 成员函数：输出书的内容   获得书的信息   修改数量  获得书的类别

  2、电子书类：                 

      （1）成员变量：书名  作者   大小  类别

      （2） 成员函数：输出书的内容   获得书的信息  获得书的类别

 3、书架类：

     （1）成员变量：书架编号   书架类别   书架上书的数量   书的总数（所有书架都能知道）

     （2）  成员函数：获得该书架书的数量   给该书架上添加书   从该书架上删除书

 4、图书管理员类：

     （1） 成员变量：姓名  年龄  性别   工号

     （2）成员函数：将书按照类别添加到书架上，将书从某个书架上删除

完成步骤：

1、定义纸质书类  电子书类   书架类   图书管理员类

2、将书的总数定义成静态成员变量

3、定义图书类，纸质书类和电子书类继承于图书类

4、在书架类中定义数组，将插入的书的信息放在数组中

   在实例化书架类对象时，可以实例化一个对象数组，方便按书的类别找到对应的书架

5、图书管理员通过不同的方式浏览电子书和纸质书

7、将书架和书的信息存放到数据库

注意：类的声明和类的成员函数的定义分别在.h和.cpp文件中。
