刚开始学习设计模式，还不是很懂，慢慢来吧，首先应该是Factory Pattern,下面是代码：
Product.h
#ifndef _PRODUCT_H_#define _PRODUCT_H_#include <iostream>using namespace std;class Product{public: virtual ~Product()=0;protected: Product();private:};class ConcreteProductA :public Product{public: ~ConcreteProductA(); ConcreteProductA();protected:private:};class ConcreteProductB :public Product{public: ~ConcreteProductB(); ConcreteProductB();protected:private:};#endif
Product.cpp
#include "Product.h"#include <iostream>using namespace std;Product::Product(){}Product::~Product(){}ConcreteProductA::ConcreteProductA(){ cout << "ConcreteProductA....." <<endl;}ConcreteProductA::~ConcreteProductA(){}ConcreteProductB::ConcreteProductB(){ cout << "ConcreteProductB....." <<endl;}ConcreteProductB::~ConcreteProductB(){}
Factory.h
#ifndef FACTORY_H_#define FACTORY_H_#include "Product.h"#include <iostream>using namespace std;class Product;class Factory{public: virtual ~Factory()=0; virtual Product* creatProductA()=0; virtual Product* creatProductB()=0;protected: Factory();private:};class ConcreteFactory:public Factory{public: ConcreteFactory(); ~ConcreteFactory(); Product* creatProductA(); Product* creatProductB();protected:private:};#endif
Factory.cpp
#include "Factory.h"#include "Product.h"#include <iostream>using namespace std;Factory::Factory(){}Factory::~Factory(){}ConcreteFactory::ConcreteFactory(){ cout << "ConcreteFactory..."<<endl;}ConcreteFactory::~ConcreteFactory(){}Product* ConcreteFactory::creatProductA(){ return new ConcreteProductA();}Product* ConcreteFactory::creatProductB(){ return new ConcreteProductB();}
main.cpp
#include <iostream>#include "Factory.h"#include "Product.h"using namespace std;int main(){ Factory* factory = new ConcreteFactory(); Product* productA = factory->creatProductA(); Product* productB = factory->creatProductB(); return 0;}
