c++,继承，也称基类，派生类，自己研究吧，很简单想法

#include <iostream>using namespace std;//基类Peopleclass People{public: People(char *name,int age); void display();protected: char *m_name; int m_age;};People::People(char *name,int age): m_name(name),m_age(age){}void People::display(){ cout<<m_name<<"今年"<<m_age<<"岁了，是个无业游民。"<<endl;}//派生类Teacherclass Teacher: public People{public: Teacher(char *name,int age,int salary); void display();private: int m_salary;};Teacher::Teacher(char *name,int salary): People(name,age),m_salary(salary){}void Teacher::display(){ cout<<m_name<<"今年"<<m_age<<"岁了，是一名教师，每月有"<<m_salary<<"元的收入。"<<endl;}int main(){ People *p = new People("王志刚",23); p -> display(); p = new Teacher("赵宏佳",45,8200); p -> display(); return 0;}
