My eyebrow raised at the leading zero as well, but I'd call it
ambiguous. 0x14 is unambiguously decimal 20, but 014 is only
unambiguous in a context that defines leading zero as implying octal.
For a C program relying on the runtime to convert text to numeric
representation, it depends. sscanf("%d", &myint) will convert 014 to
decimal 14, "%i" gets decimal 12.
I personally hunt down and kill %i and other octal-assuming code when
I see it, except where octal is conventional. To my eyes, 0xFF (or
FF) screams "all bits lit" while 0377 (or 377) only hesitantly clears
its throat. Moreover, I assume computers will be used by people who
have never had reason to believe a leading zero implies base 8, and I
find no joy in forcing them to learn that quirk of computing history.
