Hi,
Try initializing your "res" variable first.
either:
memset(&res, 0, sizeof(res));
Or:
res[0] = 0;
Both will work, it all depends if you want to write "clean" code, of
"fast" code (and your definition of both).
I believe there are cleaner way to do what you are doing, but I'll let
that to your curiosity.
