 * 版 本 号：      201158504431

 * 对任务及求解方法的描述部分

 * 输入描述： 1）在两个基类中都包含姓名、年龄、性别、地址、电话等数据成员。 

 

                 （2）在Teacher类中还包含数据成员title(职称)，在Cadre类中还包 含数据成员post（职务），在Teacher_Cadre类中还包含 数据成员                          wages(工资)。 

 

                 （3）对两个基类中的姓名、年龄、性别、地址、电话 等数据成员用相同的名字，在引用这些数据成员时，指定作用域。

 

                （4）在类体中声明成员函数，在类外定义成员函数。

 

                （5）在派生类Teacher_Cadre的成员函数show中调用Teacher类中的display函数，输出姓名、年龄、性别、职称、地址、电话，然后再用                     cout语句输出职务与工资。
