实验4：抽象工厂模式

本次实验属于模仿型实验，通过本次实验学生将掌握以下内容：

1、理解抽象工厂模式的动机，掌握该模式的结构；

2、能够利用抽象工厂模式解决实际问题。

 

[实验任务一]：人与肤色

使用抽象工厂模式，完成下述产品等级结构：

 

实验要求：

1.画出对应的类图；

2.提交源代码；

3.注意编程规范。

 

#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{

       virtual void show(){

              cout << "白皮肤的男性" << endl;

       }
