学生干部虚基类

Description

基于Student(学生)类和Cadre（干部）类，采用多重继承方式由这两个类派生出新类Student_Cadre（学生兼干部）。
这两个基类均继承自Person类，包含姓名、年龄、性别、地址、电话等数据成员。在Student类中还包含数据成员major(专业)，在Cadre类中还包含数据成员post（职务），
在Student_Cadre类中还包含数据成员wages(工资)。
注意使用虚基类使Student_Cadre只包含一份从Person类继承来的成员。

Input

学生干部的姓名，年龄，性别，专业，职位，地址，电话，薪水

修改该学生干部的新地址，新电话

Output

学生干部的信息
