WebThe C++ language does not include a data type that allows us to represent a single bit. Instead, we have to work with groups of bits. The smallest group of bits the language allows use to work with is the unsigned char, which is a group of 8 bits.

WebThe number of bits in a byte is given by CHAR_BIT, which is defined in climits and required to be at least 8. While most modern systems have 8-bit bytes, and POSIX requires CHAR_BIT to be exactly 8, there are some systems where CHAR_BIT is greater than 8 i.e a single byte may be comprised of 8, 16, 32 or 64 bits.
