I'm not sure why you posted this.

The original poster asked a Java question. Your code is C. Your code does something totally different, not even solving the same problem.

I won't go into various formatting and user experience issues, but I'd like to point out an important problem with your code: you assume the user won't enter a size that's larger than 1000. If they do, memory corruption will happen.
