同样是设计模式中的迷宫问题

class EnchantedMazeGame:public MazeGame
{
public:
	EnchantedMazeGame()
	{
		cout<<"You have created a EnchantedMazeGame!\n";
	}

	virtual Room* MakeRoom(int n) const
	{ 
		return new EnchantedRoom(n,CastSpell()); 
	}
	virtual Door* MakeDoor(Room* r1,Room* r2) const
	{
		return new DoorNeedingSpell(r1,r2); 
	}
protected:
	Spell* CastSpell() const
	{
		return new Spell;
	}	
};
