根据cocos2d-x的代理模式，仿写一遍。

class CCApplicationProtocol{public:      virtual bool applicationDIDFinishLaunching() = 0;};class CCApplication :public CCApplicationProtocol{public:    static CCApplication* instance ;    CCApplication()    {        //这里的this是CCApplication子类里面的对象        instance =  this;    }    ~CCApplication()    {    }    voID run()    {        applicationDIDFinishLaunching();    }    static CCApplication* getInstance()    {        return instance;    }};CCApplication* CCApplication::instance = NulL;/** * @brIEf The AndroID class * androID 平台实现 */class AndroID:private CCApplication{public:    bool applicationDIDFinishLaunching()    {        cout<<"this is androID"<<endl;        return true;    }};/** * @brIEf The linux class * linux 平台的实现 */class linux:private CCApplication{public:    bool applicationDIDFinishLaunching()    {        cout<<"this is linux"<<endl;        return true;    }};/** * @brIEf The Ios class * IOS 平台的实现 */class Ios:private CCApplication{public:    bool applicationDIDFinishLaunching()    {        cout<<"this is IOS"<<endl;        return true;    }};/** * @brIEf The Ios class * win32 平台的实现 */class windows:private CCApplication{public:    bool applicationDIDFinishLaunching()    {        cout<<"this is windows"<<endl;        return true;    }};
