派生类定义：根据所给的基类，完成多重继承下的派生类定义

函数接口定义：

#include

#include

using namespace std;

//定义公共基类Person

class Person                              

{public:

  Person(string nam,char s,int a)              

   {name=nam;sex=s;age=a;}

 protected:                              

   string name;

   char sex;

   int age;

};

//定义类Teacher

class Teacher:virtual public Person              

 {public:                                 

   Teacher(string nam,char s,int a,string t):Person(nam,s,a)       

    {title=t; 

    }

  protected:                                   

    string title;                                

};

//定义类Student

class Student:virtual public Person               

 {public:

   Student(string nam,char s,int a,float sco):   

      Person(nam,s,a),score(sco){}              

  protected:                                     

    float score;                               

 };

 /*这里添加派生类的定义*/

裁判测试程序样例：

int main( )

 {Graduate grad1("Wang-li",'f',24,"assistant",89.5,1234.5);

  grad1.show( );

  return 0;

}

输出样例：

在这里给出相应的输出。例如：

name:Wang-li

age:24

sex:f

score:89.5

title:assistant

wages:1234.5
