    Someone help me a bit here. [ inheritance ]

    Code:
    class CEntity {
    public:	
    	CEntity ();
    	virtual	   ~CEntity ();
    	void	   calc_dmg (CEntity &obj);
    
    
    };
    
    class CPlayer : public CEntity {
    
    };
    
    class CBattlePlayer : public CPlayer {
    
    };
    
    class CEnemy : public CEntity {
    
    };
    Now say I have:

    CEnemy monster;
    CBattlePlayer player;

    can I call player.calc_dmg (monster)?
    How is inheritance aligned with polymorphism, or is it not? Heh...

    As long as the function was declared public in the base class then yes you can call it from a derived object. Or you can override it in your derived class and have that function call it by using the base class name the scope operator( :: ) and the function using ur example it would be:

    void CBattlePlayer::calc_dmg(CEntity& obj)
    { CEntity::calc_dmg(CEntity);
    }
