inheritance II

still figuring out but trying to find the best way to allow maintain a list of derived classes in a base class ...

class Base
{
	public:
	virtual void v1() = 0;
	virtual void v2() = 0;
};

#pragma once
#include "Base.h"
class D0 : Base
	private:
	void v1();
	void v2();
	void addD2();
	std::deque<D0*> m_pD2;
};

#pragma once
#include "d0.h"
class d1 : d0
	virtual void v3() = 0;
	virtual void v4() = 0;
};

#pragma once
#include "d1.h"
class d2 : d1
	protected:
	void v3();
	void v4();
};

from an instance of D0 I add D2 instances to deque?
