【1】什么是桥接模式？

【2】桥接模式的代码示例

示例代码：

1 #include 
      
        2 #include 
       
         3 using namespace std; 4  5 class HandsetSoft 6 { 7 public: 8     virtual void run() = 0; 9 };10 11 class HandsetGame : public HandsetSoft12 {13 public:14     void run()15     {16         cout << "运行手机游戏" << endl;17     }18 };19 20 class HandsetAddressList : public HandsetSoft21 {22 public:23     void run()24     {25         cout << "运行手机通讯录" << endl;26     }27 };28 29 class HandsetBrand30 {31 protected:32     HandsetSoft *soft;33 public:34     void setHandsetSoft(HandsetSoft *soft)35     {36         this->soft = soft;37     }38     virtual void run() = 0;39 };40 41 class HandsetBrandN : public HandsetBrand42 {43 public:44     void run()45     {46         soft->run();47     }48 };49 50 class HandsetBrandM : public HandsetBrand51 {52 public:53     void run()54     {55         soft->run();56     }57 };58 59 int main()60 {61     HandsetBrand *hb;62     hb = new HandsetBrandM();63     64     hb->setHandsetSoft(new HandsetGame());65     hb->run();66     hb->setHandsetSoft(new HandsetAddressList());67     hb->run();68 69     return 0;70 }
