When two or more classes serve as base classes in multiple inheritance, you want to choose a distinct name for each member function in order to avoid name ambiguity:

 class AudioStreamer {//real-time sound playerpublic:void Play();void Stop();};  class VideoStreamer {//real-time video playerpublic:void Play();void Stop();}; class AudioVisual: public AudioStreamer, public VideoStreamer {/*_*/};AudioVisual player;player.play(); //error:  is AudioStreamer::play() or VideoStreamer::play() to be invoked?

One way to overcome this ambiguity is to specify the full-qualified name of a member function:

  	Player.AudioStreamer::play(); //fine but tedious

However, a preferable solution is the use of distinct method names in the base classes:

 class AudioStreamer {public:void au_Play(); };  class VideoStreamer {public:void vd_Play(); }; 	Player.au_play(); //now distinct: play sound
