#print
Write a program which reads two numbers and
prints the larger one in decimal. Use the same
"getnum" subroutine.  Compile, test and type
"ready" as usual.

/*	One way: */

main() {
	int n1, n2;

	n1 = getnum();
	n2 = getnum();
	printf("%d\n", n1 > n2 ? n1 : n2);
}

/* You could also use something like

	if (n1 > n2)
		printf("%d\n", n1);
	else
		printf("%d\n", n2);
