MFC学习之路(八) 关于多态

#include <iostream>
using namespace std;

class Parent
{
public:
	Parent()
	{
	}
	~Parent()
	{
	}
	void fun()
	{
		print();
	}
	virtual void print()
	{
		cout << "parent" << endl;
	}
};

class Sun : public Parent
{
	void print()
	{
		cout << "Sun" << endl;
	}
};

int main(int argc, char *agrv[])
{
	Sun s;
	s.fun();
	while(1);

	return 0;
}

 

结果打印:：Sun
