【1】什么是桥接模式？【2】桥接模式的代码示例示例代码：

 

#include 
     
      #include 
      
       using namespace std;class HandsetSoft{public:    virtual void run() = 0;};class HandsetGame : public HandsetSoft{public:    void run()    {        cout << "运行手机游戏" << endl;    }};class HandsetAddressList : public HandsetSoft{public:    void run()    {        cout << "运行手机通讯录" << endl;    }};class HandsetBrand{protected:    HandsetSoft *soft;public:    void setHandsetSoft(HandsetSoft *soft)    {        this->soft = soft;    }    virtual void run() = 0;};class HandsetBrandN : public HandsetBrand{public:    void run()    {        soft->run();    }};class HandsetBrandM : public HandsetBrand{public:    void run()    {        soft->run();    }};int main(){    HandsetBrand *hb;    hb = new HandsetBrandM();        hb->setHandsetSoft(new HandsetGame());    hb->run();    hb->setHandsetSoft(new HandsetAddressList());    hb->run();    return 0;}
