> Signed and unsigned are actually treated internally the same on computers. if you are writing code in C or C++ the computer you are programming for is the C / C++ abstract machine. C++ recently sanctified complement-of-two as integer representation, but C does not and supports machines with one's complement representation.

One's complement is on its way out in C too. The next C standard will require two's complement.
