C++工厂方法模式

#include <iostream>

using namespace std;

class Plant //工厂
{
public:

	virtual void ShowName() = 0;
};

class  Lamborghini :public Plant //兰博基尼工厂
{
public:
	void ShowName() {
		cout << "兰博基尼工厂生产的超跑" << endl;
	}
};

class  Ferrari :public Plant //法拉利工厂
{
public:
	void ShowName() {
		cout << "法拉利工厂生产的超跑" << endl;
	}
};

class  Bugatti :public Plant //布加迪工厂
{
public:
	void ShowName() {
		cout << "布加迪工厂生产的超跑" << endl;
	}
};

class SynthesizePlant {
public:
	virtual Plant*CreatePlant() = 0;

};

class LamborghiniPlant :public SynthesizePlant
{
public:
	Plant* CreatePlant() {
		return new Lamborghini;
	}
};


class FerrariPlant :public SynthesizePlant
{
public:
	Plant* CreatePlant() {
		return new Ferrari;
	}
};

class BugattiPlant :public SynthesizePlant
{
public:
	Plant* CreatePlant() {
		return new Bugatti;
	}
};

void test() {
	SynthesizePlant*Splant =NULL;
	Plant*myPlant = NULL;

	Splant = new LamborghiniPlant;
	myPlant = Splant->CreatePlant();
	myPlant->ShowName();
	delete Splant;
	delete myPlant;

	Splant = new FerrariPlant;
	myPlant = Splant->CreatePlant();
	myPlant->ShowName();
	delete Splant;
	delete myPlant;

	Splant = new BugattiPlant;
	myPlant = Splant->CreatePlant();
	myPlant->ShowName();
	delete Splant;
	delete myPlant;
}

void main() {
	test();
