擴充卡模式

          今天來學習一下擴充卡模式，下面看一下C++的實作。

//擴充卡模式
class Player
{
public:
	virtual void Attack() 
	{
		return;
	}
	virtual void Defense() 
	{
		return;
	}

	string s_name;
};

class Forwards : public Player
{
public:
	Forwards(string name)
	{
		s_name = name;
	}

	void Attack()
	{
		cout << s_name << "," << "Attack" << endl;
	}

	void Defense() 
	{
		cout << s_name << "," << "Defense" << endl;
	}
};


class ForwardCentor 
{
public:
	void jingong()
	{
		cout << "進攻" << endl;
	}

	void fangshou()
	{
		cout << "防守" << endl;
	}
};

class Translator : public Player
{
public:
	Translator(string name) 
	{
		wjzf = new ForwardCentor();
		s_name = name;
	}

	void Attack()
	{
		cout << s_name;
		wjzf->jingong();
	}

	void Defense()
	{
		cout << s_name ;
		wjzf->fangshou();
	}

private:
	ForwardCentor *wjzf;
};



int main()
{
	
	Player *b = new Forwards("kebi");
	b->Attack();

	Player *ym = new Translator("yaoming");
	ym->Attack();

        delete b;
        delete ym;
	return 0;
}
