【项目2 - 教师兼干部类】(第11章习题9)分别定义Teacher(教师)类和Cadre(干部)类,採用多重继承方式由这两个类派生出新类Teacher_Cadre(教师兼干部——这个俗称双肩挑)。要求:
(1)在两个基类中都包括姓名、年龄、性别、地址、电话等数据成员。
(2)在Teacher类中还包括数据成员title(职称),在Cadre类中还包括数据成员post(职务),在Teacher_Cadre类中还包括数据成员wages(工资)。
(3)对两个基类中的姓名、年龄、性别、地址、电话等数据成员用同样的名字,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。
