The next test was this: x and FF = ? x or FF = ? x xor FF = ? Only one of 5 candidates could solve the first two!

(I notice you said "programming experience" above and not > "C experience".) The question was: take any language you know or explain verbally. The opinions were divided between: "it is impossible to do," and "there must be a library function for this, I don't remember which." -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
