C++多态的实现

#include <iostream>
using namespace std;
class myjob
{
public:
  virtual void say()
  {
    cout<<"i am virtual function!"<<endl;
  }

};
class son:public myjob
{
public:
  virtual void say()
  {
    cout<<"i am son!"<<endl;
  }
};
class daughter:public myjob
{
public:
  virtual void say()
  {
    cout<<"i am daughter!"<<endl;
  }
};

int main()
{
  //将子类对象指针赋给父类
  myjob* father=new son();
  //调用虚函数
  father->say();

  return 0;
}
