这里写图片描述
#include <iostream>class AbstractProductA{public:    virtual ~AbstractProductA(){}protected:    AbstractProductA(){}};class AbstractProductB{public:    virtual ~AbstractProductB(){}protected:    AbstractProductB(){}};class ProductA1:public AbstractProductA{public:    ProductA1(){ std::cout << "ProductA1...."<< std::endl;}    ~ProductA1(){}};class ProductA2:public AbstractProductA{public:    ProductA2(){std::cout << "ProductA2...."<< std::endl;}    ~ProductA2(){}};class ProductB1:public AbstractProductB{public:    ProductB1(){std::cout << "ProductB1...."<< std::endl;}    ~ProductB1(){}};class ProductB2:public AbstractProductB{public:    ProductB2(){std::cout << "ProductB2...."<< std::endl;}    ~ProductB2(){}};//-----------------------------------------------------------------class AbstractFactory{public:    virtual AbstractProductA* CreateProductA()=0;    virtual AbstractProductB* CreateProductB()=0;    virtual ~AbstractFactory(){}protected:    AbstractFactory(){}};class CreateFactory1 : public AbstractFactory{public:    CreateFactory1(){}    ~CreateFactory1(){}    AbstractProductA *CreateProductA(){ return new ProductA1;}    AbstractProductB *CreateProductB(){ return new ProductB1;}};class CreateFactory2:public AbstractFactory{public:    CreateFactory2(){}    ~CreateFactory2(){}    AbstractProductA *CreateProductA(){ return new ProductA2;}    AbstractProductB *CreateProductB(){ return new ProductB2;}};int main(){    AbstractFactory *f1 = new CreateFactory1();    f1->CreateProductA();    f1->CreateProductB();    AbstractFactory *f2 = new CreateFactory2();    f2->CreateProductA();    f2->CreateProductB();    return 0;}
