WebJan 26, 2015 · The bitwise operators promote small integers (such as char) to signed ints. Isn't there an issue with this promotion to signed ints when bitwise operators often gives undefined or implementation-defined behaviour on signed operator types? Why wouldn't the standard promote char to unsigned int? WebJan 16, 2024 · O.1 — Bit flags and bit manipulation via std::bitset. On modern computer architectures, the smallest addressable unit of memory is a byte. Since all objects need to have unique memory addresses, this means objects must be at least one byte in size. For most variable types, this is fine. However, for Boolean values, this is a bit wasteful (pun ...
