: AHA! But what if it WAS a function?  And what if it was some sort of very
: heavily used function?  In THAT case wouldn't that fact that you saved
: that extra useless code be worth something?

Are you brain-dead? Or just blind? (Like me?) This is also from the
article you quoted:

	for (i = 0; i < N; ++i) {
		for (j = 0; X[i][j] == 0; ) {
			if (++j == N) {
				printf("The first all-zero row is %d\n", i);
				return;
			}
		}
	}

And is perfectly appropriate for putting into a function.
