I'm wondering if I'm using unsigned integers (specifically NSUInteger) properly or not.

I was under the impression that unsigned integers run from 0 to MAX_INT, but when I use them in a "for" loop within these bounds, the loop does not seem to always obey these constraints.

For example:

for (NSUInteger counter = 5; counter >= 0; --counter)
{
	NSLog(@"NSUInteger: %d", counter);
}

keeps running well after the "counter" variable turns negative:


NSUInteger runs from 0 -> NSUIntegerMax.

This is how you print a NSUInteger:

	NSLog(@"NSUInteger: %lu", ((unsigned long)counter));
