问题描述：
使用抽象工厂模式，完成下述产品等级结构：
C++代码：
#include<iostream>
using namespace std;
//抽象产品类——Man类
class Man{
public:
virtual void show() = 0;
};
//抽象产品类——Woman类
class Woman{
public:
virtual void show() = 0;
};
//具体产品类——YellowMan类
class YellowMan : public Man{
public:
virtual void show(){
cout << "黄皮肤的男性" << endl;
}
};
//具体产品类——BlackMan类
class BlackMan : public Man{
public:
virtual void show(){
cout << "黑皮肤的男性" << endl;
}
};
//具体产品类——WhiteMan类
class WhiteMan : public Man{
public:
virtual void show(){
cout << "白皮肤的男性" << endl;
}
};
//具体产品类——YellowWoman类
class YellowWoman : public Woman{
public:
virtual void show(){
cout << "黄皮肤的女性" << endl;
}
};
//具体产品类——BlackWoman类
class BlackWoman : public Woman{
public:
virtual void show(){
cout << "黑皮肤的女性" << endl;
}
};
//具体产品类——WhiteWoman类
class WhiteWoman : public Woman{
public:
virtual void show(){
cout << "白皮肤的女性" << endl;
}
};
//抽象工厂类——AbstractFactory类
class AbstractFactory{
public:
virtual Man* produceMan() = 0;
virtual Woman* produceWoman() = 0;
};
//具体工厂类——YellowFactory类
class YellowFactory : public AbstractFactory{
public:
virtual Man* produceMan(){
return new YellowMan();
}
virtual Woman* produceWoman(){
return new YellowWoman();
}
};
//具体工厂类——BlackFactory类
class BlackFactory : public AbstractFactory{
public:
virtual Man* produceMan(){
return new BlackMan();
}
virtual Woman* produceWoman(){
return new BlackWoman();
}
};
//具体工厂类——WhiteFactory类
class WhiteFactory : public AbstractFactory{
public:
virtual Man* produceMan(){
return new WhiteMan();
}
virtual Woman* produceWoman(){
return new WhiteWoman();
}
};
//测试类——test类
void test(){
//黄皮肤工厂
AbstractFactory* factory = NULL;
factory = new YellowFactory;
Man* man = factory->produceMan();
man->show();
delete man;
man = NULL;
Woman* woman = factory->produceWoman();
woman->show();
delete woman;
woman = NULL;
delete factory;
factory = NULL;
cout<<"*************************"<<endl;
//黑皮肤工厂
factory = new BlackFactory;
man = factory->produceMan();
man->show();
delete man;
man = NULL;
woman = factory->produceWoman();
woman->show();
delete woman;
woman = NULL;
delete factory;
factory = NULL;
cout<<"*************************"<<endl;
//白皮肤工厂
factory = new WhiteFactory;
man = factory->produceMan();
man->show();
delete man;
man = NULL;
woman = factory->produceWoman();
woman->show();
delete woman;
woman = NULL;
delete factory;
factory = NULL;
}
int main(){
test();
return 0;
}
运行结果：
#include<iostream>
using namespace std;
//抽象产品类——Man类
class Man{
public:
virtual void show() = 0;
};
//抽象产品类——Woman类
class Woman{
public:
virtual void show() = 0;
};
//具体产品类——YellowMan类
class YellowMan : public Man{
public:
virtual void show(){
cout << "黄皮肤的男性" << endl;
}
};
//具体产品类——BlackMan类

public:
virtual void show(){
cout << "黑皮肤的男性" << endl;
}
};
//具体产品类——WhiteMan类
class WhiteMan : public Man{
public:
virtual void show(){
cout << "白皮肤的男性" << endl;
}
};
//具体产品类——YellowWoman类
class YellowWoman : public Woman{
public:
virtual void show(){
cout << "黄皮肤的女性" << endl;
}
};
//具体产品类——BlackWoman类
class BlackWoman : public Woman{
public:
virtual void show(){
cout << "黑皮肤的女性" << endl;
}
};
//具体产品类——WhiteWoman类
class WhiteWoman : public Woman{
public:

cout << "白皮肤的女性" << endl;
}
};

virtual Woman* produceWoman() = 0;
};
//具体工厂类——YellowFactory类
class YellowFactory : public AbstractFactory{
public:
virtual Man* produceMan(){
return new YellowMan();
}
virtual Woman* produceWoman(){
return new YellowWoman();
}
};
//具体工厂类——BlackFactory类
class BlackFactory : public AbstractFactory{
public:
virtual Man* produceMan(){
return new BlackMan();
}
virtual Woman* produceWoman(){
return new BlackWoman();
}
};
//具体工厂类——WhiteFactory类
class WhiteFactory : public AbstractFactory{
public:
virtual Man* produceMan(){
return new WhiteMan();
}
virtual Woman* produceWoman(){
return new WhiteWoman();
}
};
//测试类——test类
void test(){
//黄皮肤工厂
AbstractFactory* factory = NULL;

Man* man = factory->produceMan();
man->show();
