rand()%128 - 64

If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.

N is 128 in this case and the condition should be fulfilled...The first solution only works when N evenly divides into RAND_MAX

You never answered my question from the last thread. There's a real possibility that you want unique numbers, and getting a random number in the range [-63, 64] is the wrong way to go about that.
>N is 128 in this case and the condition should be fulfilled...
Who said RAND_MAX has to be a power of two?
My best code is written with the delete key.
