用代码和UML图化解设计模式之桥接模式的深入分析
厂家生产不同的产品。。。。产品和厂家有这组合的关系。
上代码
// Bridge.cpp : 定义控制台应用程序的入口点。
/************************************************************************/
#include "stdafx.h"
#include <iostream>
using namespace std;
class Product
{
public:

virtual ~Product(){}
virtual void make()=0;
virtual void sell()=0;
};
class ProductA:public Product
{
public:

virtual ~ProductA(){}
virtual void make()
{
cout<<"ProductA:make()"<<endl;
}
virtual void sell()
{

}
};
