簡單好玩的編程代碼：c++代碼示例大全

策略模式就是準備一組算法，並將每一個算法封裝起來，使得他們可以互換(這兒的關鍵就是算法的邏輯抽象，接口封裝到一個類中，再通過委託的方式將具體的算法實現委託給具體的類來實現)

對稱加密速度快加密大數據塊文件特點，加密密鑰和解密密鑰是一樣的

非對稱加密，加密速度慢、加密強度高高，安全性特點，加密密鑰和解密密鑰不一樣

#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;


}

中介者模式就是定義一個中介對象，未封裝系列對象之間的交互，終結者是各個對象不需要顯示的相互調用，從而使其耦合性鬆散，而且可以獨立的改變他們之間的交互

中介者問題拋出

#include<iostream>
using namespace std;
#include"string"
class Person
{
public:
	Person(string name, int sex, int condi)
	{
		m_name=name;
	    m_sex=sex;
		m_condi = condi;

	}
	string  getName()
	{
		return m_name;
	}
	int  getSex()
	{
		return m_sex;
	}
	int  getCondi()
	{
		return m_condi;
	}
protected:
	string   m_name;
	int      m_sex;
	int      m_condi;
};
class Women :public Person
{
public:
	Women(string name, int sex, int condi) :Person(name, sex, condi)
	{

	}
	virtual   void  getParter(Person*p)
	{
		if (this->m_sex == p->getSex())
		{
			cout << "我不是同性戀..(這裡就是問題研究,不帶任何感情色彩)" << endl;
		}
		if (this->getCondi() == p->getCondi())
		{
			cout << this->getName() << "和" << p->getName() << "絕配" << endl;

		}
		else
		{
			cout << this->getName() << "和" << p->getName() << "bu配" << endl;
		}
	}
};
class Man :public Person
{
public:
	Man(string name, int sex, int condi) :Person(name, sex, condi)
	{

	}
	virtual   void  getParter(Person*p)
	{
		if (this->m_sex == p->getSex())
		{
			cout << "我不是同性戀..(這裡就是問題研究,不帶任何感情色彩)" << endl;
		}
		if (this->getCondi() == p->getCondi())
		{
			cout << this->getName() << "和" << p->getName() << "絕配" << endl;

		}
		else
		{
			cout << this->getName() << "和" << p->getName() << "bu配" << endl;
		}
	}
};
void main()
{
	Person *xiaofang = new Women("小芳", 2, 5);
	Person *zhangsan = new Man("張三", 1, 4);
	Person *lisi = new Man("李四", 2, 5);
	xiaofang->getParter(zhangsan);
	xiaofang->getParter(lisi);
	system("pause");
	return;
}
