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;
}
