There must be a branch somewhere; whether it is implicit in a for-loop or
explicit with break is not terribly important. There's nothing wrong with this
chunk of code, and if you would otherwise have to duplicate the real code that
you use f(i) to represent, then it's your best option for code clarity.
I would write it as
do {
// here is the code that you are doing
// over and over throughout the loop
// that you used f(i) to represent
if (n == i) break;
i++;
} while (1);
but that's just stylistic. The whitespace before the line with the break will
grab the eye.
