I do use -Wall but for release code only, thank you for a tip.

Ok, I see, thank you.

I know how it's calculated: e.g. (-1 modulo 256) + 256 = 255, I am wondering about the internals.

Btw, "C++11 Clause 4.7 - Integral conversions" is it from the C++ standard? Where can I get?

Thanks.

Hello,

unsigned char c = -1; // c has value 255

Why is that, on a bit level? Negative sign would set the highest bit to 1, and 1 would set the lowest bit to 1: 10000001 which is...
