1. What's hard-coding? 2. What is a standards-conforming implementation? 3. What's "hand-written code"? 4. what's "objects created on the free store"? 5. I tried the escape character '\a' in my c++ program code, but no sound was emitted. Could anybody please tell me why? Thank you very much in advance!!:)
