Better solutions are possible.  Since, so far as I am aware, implementations
that do not honor the value returned by main() always report "success" when
main() is returned from, "return 0" from main() is just as good as "exit(0)"
and has the added merit of shutting up "lint" (or some equivalent compiler
warning).  For "return n" (n != 0), you probably ought to use "exit(n)"
instead, just to make sure that the error status reaches the environment.
(For n, you should use EXIT_FAILURE from <stdlib.h> or some local equivalent
in non-Standard C environments, to assure portability.)

Minimal correct "Hello" program:

#include <stdio.h>
main()	{
	printf( "Hello, world!\n" );
	return 0;
	}

Similar program showing both success and failure termination status:

#include <stdio.h>
#ifdef __STDC__
#include <stdlib.h>	/* for EXIT_FAILURE */
#else
#include "mydefs.h"	/* for EXIT_FAILURE */
#endif
main()	{
	if ( getchar() != EOF )
		printf( "Thanks, I needed that!\n" );
	else
		exit( EXIT_FAILURE );
	return 0;	/* or EXIT_SUCCESS */
	}
