They are just arithmetic quantities, like 'number of people'; no one would recommend using unsigned numbers for those kind of quantities. They have semantics of neither modular arithmetics nor bit arrays. As Stroustrup mentioned in TC++PL 4.4, usage of unsigned integer types for that kind of situation is discouraged. It also causes many problems in arithmetics mixed with signed integers. I know that it is from C and that it's too late to change anything, but I just want to hear what others have to say. -- Sungbom Kim [ Send an empty e-mail to c++-help@netlab.cs.rpi.edu for info ] [ about comp.lang.c++.moderated.
