外观模式为子系统中的一组接口提供一个一致的界面，此模式定义了一个高层接口，这个接口使得这个子系统更加容易使用

#include "stdafx.h"#include<iostream>using namespace std;class SubSystemOne{public:void MethodOne(){cout<<" this is system one "<<endl;}};class SubSystemTwo{public:void MethodTwo(){cout<<" this is system two "<<endl;}};class SubSystemThree{public:void MethodThree(){cout<<" this is system three "<<endl;}};class SubSystemFour{public:void MethodFour(){cout<<" this is system four "<<endl;}};class Facade{public:Facade(){_one = new SubSystemOne();_two = new SubSystemTwo();_three = new SubSystemThree();_four = new SubSystemFour();}void MethorA(){_one->MethodOne();_two->MethodTwo();}void MethorB(){_three->MethodThree();_four->MethodFour();}private:SubSystemOne *_one;SubSystemTwo *_two;SubSystemThree *_three;SubSystemFour * _four;};

// FacadeMode.cpp : 定义控制台应用程序的入口点。//#include "stdafx.h"#include"Facade.hpp"int _tmain(int argc, _TCHAR* argv[]){Facade *facade = new Facade();facade->MethorA();facade->MethorB();system("pause:");return 0;}
