please do consult the comp.lang.c.moderated faq and the newsgroup. these
kinds of posts are off-topic here. however, since I am already
responding to your post, I am guilty too ... why not go all the way: 

the only two valid prototypes for main are:

int main(void);
and
int main(int argc, char *argv[]);

traditionally, returning 0, or EXIT_SUCCESS from main is used to
indicate successful completion of a program, whereas any other value
indicates some error. 

my guess is you are failing to return a value from main, hence random
garbage is being returned. simply don't do that ... if you insist on
doing it, but up with the messages and other assorted potential
troubles. 

#include <stdlib.h>

int main(void)
{
  return EXIT_SUCCESS;
}

Sinan.
