设计模式实现(三): Factory Method

#include "stdafx.h"#include <iostream>// 产品class CProduct{public:virtual ~CProduct(){}virtual void Print(){std::cout << "Product" << std::endl;}};class CConcreteProduct : public CProduct{public:virtual void Print(){std::cout << "Concrete Product" << std::endl;}};// 工厂class CCreator{public:virtual CProduct* CreateProduct()= 0;public:void PrintFactory(){std::cout << "Factory" << std::endl;}};class CConcreteCreator : public CCreator{public:virtual CProduct* CreateProduct(){return new CConcreteProduct();}};// 使用void UseProduct(CCreator* pCreator){CProduct* pProduct = pCreator->CreateProduct();pProduct->Print();delete pProduct;}int _tmain(int argc, _TCHAR* argv[]){CCreator* pCreator = new CConcreteCreator();UseProduct(pCreator);delete pCreator;return 0;}
