表示是原创啊，但是是在总结了各路大婶知识的基础上：

#include <iostream>#include <memory>using namespace std;class AbstractEvent{public:virtual char* Event(char* apMsg)=0;};class AbstractMsgHandler{public:virtual void Handler(char* apAnswer)=0;};class MsgSender{public:MsgSender(AbstractEvent* apSubscribeEvent,AbstractMsgHandler* apMsgHandler):  m_pSubscribeEvent(apSubscribeEvent),m_pMsgHandler(apMsgHandler)  {  }void SendMsg(char* apMsg){char* lpAnswer = m_pSubscribeEvent->Event(apMsg);m_pMsgHandler->Handler(lpAnswer);}private:AbstractEvent* m_pSubscribeEvent;AbstractMsgHandler* m_pMsgHandler;};class ConcreteEvent:public AbstractEvent{public:char* Event(char* apMsg){return apMsg;}};class ConcreteMsgHandler:public AbstractMsgHandler{void Handler(char* apAnswer){std::cout << apAnswer << std::endl;}};int main(){std::auto_ptr<AbstractEvent> lpAbstractEvent(new ConcreteEvent());std::auto_ptr<AbstractMsgHandler> lpAbstractMsgHandler(new ConcreteMsgHandler());std::auto_ptr<MsgSender> lpMsgSender(new MsgSender(lpAbstractEvent.get(),lpAbstractMsgHandler.get()));char* lpMsg = "123";lpMsgSender->SendMsg(lpMsg);return 0;}

欢迎大家提建议。
