Because most people don't follow the rule that "always use unsigned variables unless you know that it really needs to be signed". And also because most people believe that C applies normal computer arithmetic, and they believe that normal computer arithmetic is wrapped 2's complement. (And indeed it usually is, give or take some bizarre exceptions like MAX_INT % -1) We all know better, but how tiny is the fraction of C programmers who have ever even *seen* the ANSI C spec, much less know in detail what it says? paul
