#include <iostream>
#include <windows.h>

class B
{
	public:
	virtual void printfa(void)
	{
		printf("B::printfa\n");
	}
	virtual void rePrintf(void)
	{
		printf("B::Reprintf\n");
	}

	void funca(void)
	{
		printfa();
		rePrintf();
	}

};

class D :public B
{
	 void printfa(void)
	{
		printf("D::printfa\n");
	}
};

int main(void)
{
	B *p = new D();
	p->printfa();
	p->funca();

	system("pause");
	return 0;
}

 

这道题我答对了,考验类,继承,重载
