Fine. But you should re-think the way you're using to create it.

This creates the matrix in the stack. That's bad, because the stack
has a fixed maximal size, on DOS/DJGPP (and several other platforms).
Use the heap, instead (--> 'new' or 'malloc'). Methods for creating 2D
dynamical arrays that still can be accessed by a[i][j] notation are in
the comp.lang.c FAQ.
