Factory Pattern

[img]C:\Documents and Settings\Administrator\桌面\编程\设计模式\Factory.jpg[/img]

刚开始学习设计模式，还不是很懂，慢慢来吧，首先应该是Factory Pattern,下面是代码：
Product.h

#ifndef _PRODUCT_H_
#define _PRODUCT_H_
#include <iostream>

using namespace std;

class Product
{
public:
    virtual ~Product()=0;
protected:
    Product();
    
private:
};

class ConcreteProductA :public Product
{
public:
    ~ConcreteProductA();
    ConcreteProductA();
protected:
private:
};

class ConcreteProductB :public Product
{
public:
    ~ConcreteProductB();
    ConcreteProductB();
protected:
private:
};

#endif

Product.cpp

#include "Product.h"
#include <iostream>

using namespace std;

Product::Product(){}
Product::~Product(){}

ConcreteProductA::ConcreteProductA(){
    cout << "ConcreteProductA....." <<endl;
}
ConcreteProductA::~ConcreteProductA(){

}

ConcreteProductB::ConcreteProductB(){
    cout << "ConcreteProductB....." <<endl;
}

ConcreteProductB::~ConcreteProductB(){

}

Factory.h

#ifndef FACTORY_H_
#define FACTORY_H_
#include "Product.h"
#include <iostream>
using namespace std;

class Product;

class Factory
{
public:
    virtual ~Factory()=0;
    virtual Product* creatProductA()=0;
    virtual Product* creatProductB()=0;
protected:
    Factory();
private:
};

class ConcreteFactory:public Factory
{
public:
    ConcreteFactory();
    ~ConcreteFactory();
    Product* creatProductA();
    Product* creatProductB();
protected:
private:
};
#endif

Factory.cpp

#include "Factory.h"
#include "Product.h"
#include <iostream>

using namespace std;

Factory::Factory(){

}
Factory::~Factory(){

}
ConcreteFactory::ConcreteFactory(){
    cout << "ConcreteFactory..."<<endl;
}

ConcreteFactory::~ConcreteFactory(){

}

Product* ConcreteFactory::creatProductA(){
    return new ConcreteProductA();
}

Product* ConcreteFactory::creatProductB(){
    return new ConcreteProductB();
}

main.cpp

#include <iostream>
#include "Factory.h"
#include "Product.h"

using namespace std;

int main(){
    Factory* factory = new ConcreteFactory();
    Product* productA = factory->creatProductA();
    Product* productB = factory->creatProductB();
    return 0;
}

什么东西，贴代码是没用的
