That's not a C program.  :-)

The return value of the main function of a valid C program
must be int.  And of course, your main function should
end with "return 0;" or "exit(0);" (the latter requires
"#include <stdlib.h>" at the top).

By the way, I recommend you get a copy of the C standard
and use it for reference.  You can buy a digital copy (PDF)
at  http://webstore.ansi.org/  (Search for "9899-1999"),
it's $30.  Alternatively ask Google for "C99 draft" to get
a free copy of a draft of the standard, which isn't very
different from the final standard.

You can also buy a hardcopy of the standard (i.e. a book),
but it was ~ $300 last time I looked.

Best regards
   Oliver
