Unsigned char / signed char

[Richardcavell]

Hi all. I'm learning C99. I realize that char can be either unsigned or signed depending on the implementation. However, is it possible to have both unsigned and signed char within the same program on any standard-conforming implementation?

Yes. Use unsigned char and signed char, as you require
