Either way, it is a distinct type from both unsigned char and signed char. Webstd::byte is defined in terms of unsigned char, so it isn't guaranteed to be 8 bits.. If you really need an 8-bit integer (independent of the number of bits that happen to be in a byte on any given platform), use std::uint8_t or std::uint8_t.. In practice, it probably doesn't matter because you're not likely to ever encounter a byte that isn't 8 bits, but I see no downside …
