Why do we need to fine a virtual function as private?

class base
{
public:
	void Interface()
	{
                ///some code...
                //if( some expression is true)

                   //return;
                //some code...
	}
private:
	virtual void Implementation(void)
	{
		cout<<"Haha lol I am private - Base"<<endl;
	}
};

class der:public base
{
	void Implementation(void)
	{
		cout<<"I am private too - Derived"<<endl;
	}
};

int _tmain(int argc, _TCHAR* argv[])
{
	base bs;
	bs.Interface();
	//bs.Implementation(); //No way!

	der dr;
	dr.Interface();
	//dr.Implementation(); //No way, again! (Unless you keep it public)

	return 0;

char temp[256];
CString cs;
cs.getBuffer(temp,cs.getLength());
cs.ReleaseBuffer();

Now pass the temp.
