//例11.8.多重继承# include <iostream># include <string.h>using namespace std;class Teacher//声明teacher类{public:Teacher(string nam,int a,string t)//构造函数{name=nam;age=a;title=t;}void display(){cout<<"name: "<<name<<endl;    cout<<"age: "<<age<<endl;cout<<"title: "<<title<<endl;}protected:string name;int age;string title;};//2.class Student//定义student类{public:Student( string nam,char s,float sco)//构造函数{//strcpy(name1,nam);name1=nam;sex=s;score=sco;}void display1(){cout<<"name: "<<Student::name1<<endl;cout<<"sex: "<<sex<<endl;cout<<"score: "<<score<<endl;}protected:string name1;char sex;float score;};//3.class Graduate:public Teacher,public Student//声明多重继承的派生类graduate{public:Graduate(string nam,int a,char s,string t,float sco,float w):Teacher(nam,a,t),Student(nam,s,sco),wage(w){}void show(){cout<<"name: "<<name<<endl;cout<<"age: "<<age<<endl;cout<<"sex:　"<<sex<<endl;cout<<"score: "<<score<<endl;cout<<"title: "<<title<<endl;cout<<"wages: "<<wage<<endl;}private:float wage;};int main()//main函数进行调试{Graduate grad1("wang_li",24,'f',"assistant",89.5,1200);grad1.show();return 0;}

运行结果：

说说：我把它：strcpy(name1,nam)改成name1=nam;
