c++ - when does ambiguity arise in multiple inheritance? -

एकाधिक विरासत में अस्पष्टता कब उत्पन्न होती है?

जब आप विरासत के कई रास्तेों में बेस क्लास को दोहराया है और आप इसे डालने की कोशिश कर रहे हैं या इसके सदस्य फ़ंक्शन को कॉल कर रहे हैं।

  struct A { }; संरचना बी: ए {}; स्ट्रेट सी: ए {}; संरचना डी: बी, सी {}; // ने ए को बेस क्लास डी डी के रूप में दोहराया है; ए * ए = स्टेटिक_कास्ट & lt; A * & gt; (& amp; d); / Oops    समस्या में कई उपाय हैं जो संदर्भ पर भारी निर्भर करते हैं (वर्चुअल आधार वर्गों का उपयोग करते हुए, केवल उपरोक्त कलाकारों को परिष्कृत करते हैं आदि)

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.
