策略是准备一套算法，把每个算法打包，这样就可以交换了(这里的关键是算法的逻辑抽象，接口打包成类，然后通过委托把具体的算法实现委托给具体的类)
加密速度快，加密密钥和解密密钥相同。
非对称加密，加密速度慢，加密强度高，安全特性，加密密钥和解密密钥不同。
#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 ***in(){//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;}
中介者模式是定义一个中介对象，不封装一系列对象之间的交互。终结符是不需要显示的各个对象的相互调用，使其耦合松散，相互之间的交互可以独立变化。
中介问题抛出
#include<iostream>using namespace std;#include"string"class Person{public:Person(string name, int ***, int condi){m_name=name; m_***=***;m_condi = condi;}string getName(){return m_name;}int getSex(){return m_***;}int getCondi(){return m_condi;}protected:string m_name;int m_***;int m_condi;};class Women :public Person{public:Women(string name, int ***, int condi) :Person(name, ***, condi){}virtual void getParter(Person*p){if (this->m_*** == p->getSex()){cout << "我不是同性恋..(这里就是问题研究,不带任何感***彩)" << endl;}if (this->getCondi() == p->getCondi()){cout << this->getName() << "和" << p->getName() << "绝配" << endl;}else{cout << this->getName() << "和" << p->getName() << "bu配" << endl;}}};class Man :public Person{public:Man(string name, int ***, int condi) :Person(name, ***, condi){}virtual void getParter(Person*p){if (this->m_*** == p->getSex()){cout << "我不是同性恋..(这里就是问题研究,不带任何感***彩)" << endl;}if (this->getCondi() == p->getCondi()){cout << this->getName() << "和" << p->getName() << "绝配" << endl;}else{cout << this->getName() << "和" << p->getName() << "bu配" << endl;}}};void ***in(){Person *xiaofang = new Women("小芳", 2, 5);Person *zhangsan = new Man("张三", 1, 4);Person *lisi = new Man("李四", 2, 5);xiaofang->getParter(zhangsan);xiaofang->getParter(lisi);system("pause");return;}
中介代码实现
#include<iostream>using namespace std;#include"string"class Person{public:Person(string name, int ***, int condi, Mediator*m){m_name = name;m_*** = ***;m_condi = condi;mediator = m;}string getName(){return m_name;}int getSex(){return m_***;}int getCondi(){return m_condi;}protected:string m_name;int m_***;int m_condi;Mediator mediator;};class Mediator//中介这的抽象父类{public:virtual void getParter() = 0;void setMan(Person*pMan){pMan = ***n;}void setWomen(Person*pMan){pWomen = women;}public:virtual void getParter(){if (pWomen->getSex() == pMan->getSex()){cout << "我不是同性恋..(这里就是问题研究,不带任何感***彩)" << endl;}if (pWomen->getCondi() == pMan->getCondi()){cout << pWomen->getName() << "和" << pMan->getName() << "绝配" << endl;}else{cout << pWomen->getName() << "和" << pMan->getName() << "bu配" << endl;}}private:Person *pWomen;Person *pMan;};class Women :public Person{public:Women(string name, int ***, int condi, Mediator*m) :Person(name, ***, condi,m){}public:virtual void getParter(Person*p){mediator->setMan(p);mediator->setWomen(this);mediator->getParter();}};class Man :public Person{public:Man(string name, int ***, int condi, Mediator*m) :Person(name, ***, condi,m){}public:virtual void getParter(Person*p){mediator->setMan(this);mediator->setWomen(p);mediator->getParter();}};void ***in(){Mediator *m = new Mediator;Person *xiaofang = new Women("小芳", 2, 5,m);Person *zhangsan = new Man("张三", 1, 4,m);Person *lisi = new Man("李四", 2, 5,m);xiaofang->getParter(zhangsan);xiaofang->getParter(lisi);system("pause");return;}
