35mm接口及25mm接口；USB Type-C接口；lighting接口 分别用类模式和对象模式实现耳机接口的转换 给出以上c++代码和类图

类模式实现：

class HeadphoneInterface {
public:
    virtual void play() = 0;
    virtual void pause() = 0;
    virtual void stop() = 0;
};

class ThreePointFiveInterface : public HeadphoneInterface {
public:
    void play() override {
        // 3.5mm接口播放实现
    }
    void pause() override {
        // 3.5mm接口暂停实现
    }
    void stop() override {
        // 3.5mm接口停止实现
    }
};

class TwoPointFiveInterface : public HeadphoneInterface {
public:
    void play() override {
        // 2.5mm接口播放实现
    }
    void pause() override {
        // 2.5mm接口暂停实现
    }
    void stop() override {
        // 2.5mm接口停止实现
    }
};

class USBTypeCInterface : public HeadphoneInterface {
public:
    void play() override {
        // USB Type-C接口播放实现
    }
    void pause() override {
        // USB Type-C接口暂停实现
    }
    void stop() override {
        // USB Type-C接口停止实现
    }
};

class LightingInterface : public HeadphoneInterface {
public:
    void play() override {
        // lighting接口播放实现
    }
    void pause() override {
        // lighting接口暂停实现
    }
    void stop() override {
        // lighting接口停止实现
    }
};

class HeadphoneAdapter {
public:
    virtual HeadphoneInterface* getInterface() = 0;
};

class ThreePointFiveAdapter : public HeadphoneAdapter {
public:
    HeadphoneInterface* getInterface() override {
        return new ThreePointFiveInterface();
    }
};

class TwoPointFiveAdapter : public HeadphoneAdapter {
public:
    HeadphoneInterface* getInterface() override {
        return new TwoPointFiveInterface();
    }
};

class USBTypeCAdapter : public HeadphoneAdapter {
public:
    HeadphoneInterface* getInterface() override {
        return new USBTypeCInterface();
    }
};

class LightingAdapter : public HeadphoneAdapter {
public:
    HeadphoneInterface* getInterface() override {
        return new LightingInterface();
    }
};

对象模式实现：

class HeadphoneInterface {
public:
    virtual void play() = 0;
    virtual void pause() = 0;
    virtual void stop() = 0;
};

class ThreePointFiveInterface : public HeadphoneInterface {
public:
    void play() override {
        // 3.5mm接口播放实现
    }
    void pause() override {
        // 3.5mm接口暂停实现
    }
    void stop() override {
        // 3.5mm接口停止实现
    }
};

class TwoPointFiveInterface : public HeadphoneInterface {
public:
    void play() override {
        // 2.5mm接口播放实现
    }
    void pause() override {
        // 2.5mm接口暂停实现
    }
    void stop() override {
        // 2.5mm接口停止实现
    }
};

class USBTypeCInterface : public HeadphoneInterface {
public:
    void play() override {
        // USB Type-C接口播放实现
    }
    void pause() override {
        // USB Type-C接口暂停实现
    }
    void stop() override {
        // USB Type-C接口停止实现
    }
};

class LightingInterface : public HeadphoneInterface {
public:
    void play() override {
        // lighting接口播放实现
    }
    void pause() override {
        // lighting接口暂停实现
    }
    void stop() override {
        // lighting接口停止实现
    }
};

class HeadphoneAdapter {
public:
    virtual HeadphoneInterface* getInterface() = 0;
};

class ThreePointFiveAdapter : public HeadphoneAdapter {
private:
    ThreePointFiveInterface interface;
public:
    HeadphoneInterface* getInterface() override {
        return &interface;
    }
};

class TwoPointFiveAdapter : public HeadphoneAdapter {
private:
    TwoPointFiveInterface interface;
public:
    HeadphoneInterface* getInterface() override {
        return &interface;
    }
};

class USBTypeCAdapter : public HeadphoneAdapter {
private:
    USBTypeCInterface interface;
public:
    HeadphoneInterface* getInterface() override {
        return &interface;
    }
};

class LightingAdapter : public HeadphoneAdapter {
private:
    LightingInterface interface;
public:
    HeadphoneInterface* getInterface() override {
        return &interface;
    }
};
