c++代码示例大全（简单好玩的编程代码）

策略模式就是准备一组算法，并将每一个算法封装起来，使得他们可以互换(这儿的关键就是算法的逻辑抽象，接口封装到一个类中，再通过委托的方式将具体的算法实现委托给具体的类来实现)，现在小编就来说说关于c++代码示例大全?下面内容希望能帮助到你，我们来一起看看吧!

对称加密速度快加密大数据块文件特点，加密密钥和解密密钥是一样的

非对称加密，加密速度慢、加密强度高高，安全性特点，加密密钥和解密密钥不一样

#include<iostream>using namespace std;class Strategy{public:	virtual void crypy() = 0;};class AES :public Strategy{public:	virtual void crypy()	{		cout << "AES加密算法 " << endl;	}};class DES :public Strategy{public:	virtual void crypy()	{		cout << " DES加密算法" << endl;	}};class Context{public:	void setStrategy(Strategy *strategy)	{		this->strategy = strategy;	}	void myoperator()	{		strategy->crypy();	}private:	Strategy *strategy;};void main(){	//	DES	*des = new DES;	des->crypy();	delete des;	Strategy*strategy = NULL;	strategy= new DES;	Context *context = new Context;	context->setStrategy(strategy);	context->myoperator();	delete strategy;	delete context;	system("pause");	return;}

  
  

	
	中介者模式就是定义一个中介对象，未封装系列对象之间的交互，终结者是各个对象不需要显示的相互调用，从而使其耦合性松散，而且可以独立的改变他们之间的交互
