4 completely different questions.  Why not ask 4 questions?

3) What is the difference between memcopy and memmove ?

'memmove' checks for overlap and chooses the correct order if overlap is detected.

'memcpy' does not and is therefore very slightly faster.

It's not the points - Just much simpler to have 4 questions.  Easier for you, easier for the experts here and easier for anyone else that, in future, has the same question.  I just wondered was there a specific reason you didn't want to ask 4 separate questions

Nothing as such...I just want the answers to all questions at one place for me to refer and no other reason other than this....
