设计模式-工厂模式的理解

代码的逻辑：

class Phone  //纯虚手机产品类，提供接口

{

public:

virtual void call(string number) = 0;

};

class IosPhone :public Phone//产品类，继承纯虚类，并实现接口

{

public:

virtual  void call(string number)

{

cout<<"IosPhone is calling,,,"<<endl;

}

};

class AndroidPhone :public Phone//产品类，继承纯虚类，并实现接口

{

public:
virtual void call(string number)

{

cout<<"AndroidPhone is calling"<<endl;

}

};

class PhoneFactory//纯虚手机工厂类，提供接口

{

public:

virtual Phone* CreatePhone()=0;

};

class IosPhoneFactory :public PhoneFactory//手机工厂类，继承纯虚类，实现接口

{

public:

virutal Phone* CreatePhone()

{

return new IosPhone();

}

};

class AndroidPhoneFactory :public PhoneFactory//手机工厂类，继承纯虚类，实现接口(创建手机)

{

public:
virutal void CreatePhone()

{

return new AndroidPhone();
}

}

void main()

{

PhoneFactory *IosPhoneCreator = new IosPhoneFactory();

PhoneFactory *AndroidPhoneCreator = new AndroidPhoneFactory();

Phone * IosPhone = IosPhoneCreator->CreatePhone();

Phone * AndroidPhone = AndroidPhoneCreator->CreatePhone();

}
