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)
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
中介者问题抛出
#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 << "我不是同性恋..(这里就是问题研究,不带任何感情色彩)" << 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 sex, int condi) :Person(name, sex, condi)
{
}
virtual void getParter(Person*p)
{
if (this->m_sex == p->getSex())
{
cout << "我不是同性恋..(这里就是问题研究,不带任何感情色彩)" << 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 main()
{
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");
