Does this depend on the C++ version, OS, and/or system architecture? Does long, long long, int, short, and even custom integer types from all/most packages, use the same sign system?

I am learning about shifting, masking, and other forms of bit-manipulation, so this will help.

    Caution, that even though the two's complement is *now* guaranteed, you can still run afoul of **undefined behavior** with shifting. Best to do bit twiddling with unsigned integers. – Eljay Nov 23 '22 at 20:17
