【项目2】分别定义Teacher(教师)类和Cadre(干部)类,采用多重继承方式由这两个类派生出新类Teacher_Cadre(教师兼干部)。要求:
(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。
参考解答:
