- 类的定义
类中包含描述属性的数据成员和定义行为的成员函数的函数原型，不仅可以直观的看到程序中该类定义的数据成员以及将要实现的功能，因此，该程序均通过类外实现各个功能。
对类的定义如下：
（1）图书管理模块：
①图书类class book
②图书数据库类class bdatabase
（2）图书管理员模块：
①图书管理员类class librarian
②图书管理员数据库类class ldatabase
（3）读者管理模块：
①读者类class reader
②读者数据库类class rdatabase
2、相关构造函数、成员函数
通过相关成员函数和构造函数可以分别实现不同的详细功能
（1）图书管理模块：
①图书类
| book (){} //构造函数 void setno (int n); /图书编号取值 int getno (); //返回图书编号值 void setprice (int p); //图书价格取值 int getprice (); //返回图书价格值 void setname (char na[]); //字符串复制 char* getname (); //返回图书名称 void setauthor (char a[]); //字符串复制 char* getauthor (); //返回图书作者 void borbook (); //借书标志 void delbook (); //删除图书标志 void addbook (int no, char na[], char author[], int price) ; //实现增加图书的功能（便于图书管理员） |
②图书数据库类
| bdatabase (){} //构造函数 ~bdatabase (); //析构函数 void openfile (); //打开文件函数 void addbooks (); //向数据库添加图书 int findbooks (int suffix); //查找数据库的图书，用于借书时查找 int findbooks (); //查找图书，用于图书维护查找 void editbooks (); //编辑（修改）数据库中的图书 void delbooks (); //删除数据库中的图书 void listbooks (); //显示全部图书 |
（2）图书管理员模块
①图书管理员类
| void addlibrarian (int id, char na[], int s, char pass[]); |
//增加管理员
②图书管理员数据库类
| ldatabase (){} //构造函数 ~ldatabase (); //析构函数 void openfile1 (); //打开文件的函数 void addlibrarians (); //增加图书管理员 int findlibrarians (); //查找图书管理员 void editlibrarians (); //编辑（修改）图书管理员 void dellibrarians (); //删除图书管理员 void listlibrarians (); //显示图书管理员的信息 |
（3）读者管理模块
①读者类
| void addreader (int id, char na[], int s, int b, int a, char pass[]); //增加读者 void setbrbook (book bt); //设置借书标记 book getbrbook (); //返回借书信息 |
②读者数据库类
| rdatabase (){} //构造函数 ~rdatabase (); //析构函数 void openfile2 (); //打开文件 void addreaders ( int t ); //添加读者 int findreaders ( int suffix ); //查找读者 int findreaders (); //查找读者 void editreaders (); //编辑读者信息 void delreaders (); //删除读者 void listreaders ( int t ); //显示所有读者
|
（4）其他自定义函数
| void borrowtoreturn()； //借书还书函数.参数br用来判断是“借书”还是“还书”.1为“借书”,2为“还书” void booksmanage()； //图书管理员的实现 void studentmanage()； //对学生的管理 void teachermanage()； //对老师的管理 void librarianmanage()； //对图书管理员的管理 void adminmanage()； //验证系统管理员身份
