There is one more method though,
accept an 'argv' like array as the argument to your function.
as in,

int number_args (a)
char **a;
{
	int n;

	for (n = 0 ; a[n] ; n++)
	    ;

	return n;
}

And if you malloc and realloc the char * array, this size can
change at runtime, while the varargs approach is fixed at compile time.
