{
 public:
   state();
   virtual ~state();
   virtaul   void ShowState();
};
class childA:public state
{
  public:
    childA();

    void ShowState();
    void changeState(Context *pCtxt;)
        {pCtxt->changeState(new childB());}
};
class childB:public state
{
  public:
    childB();

    void ShowState();
    void changeState(Context *pCtxt)

class father
{
 public:
   void method() //方法
   {
     fun1();
     fun2();
   }
 protected:
   virtual void fun1()=0; //细节1
   virtaul void fun2()=0; //细节2
};
class child:public father
{
  private:                //实现细节.
    void fun1()
     {}
    void fun2()
     {}
}
调用代码:
 father *pc=new child;
 pc->method();
 
缺点:代码复用性不强.
strategy模式采用的是类组合的方式实现.
class strategy
{
 public:
   virtual void operation()=0;   
};
class child:public strategy
{
  public;
     void operation()
      {}
};
class X
{
  public:
    void method()
     {p->operation();}
  private:
     strategy *p;
};
