Put the "--" in the condition. It's less ugly.

  Pedantically, that doesn't properly invert post-increment in the loop step. It decrements one extra time. If I need to use the loop index after the loop, then decrementing in the condition would cause problems. size_t i = size; while(i-- > 0){ // loop body, possibly break } use(i); // i wraps below 0 size_t i = size; while(i > 0){ i--; // loop body, possibly break } use(i); // i doesn't wrap Practically, i leaves the for-loop scope, so most never encounter this problem.
