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.

WebEach bit position can be accessed individually: for example, for a given bitset named foo, the expression foo [3] accesses its fourth bit, just like a regular array accesses its elements. But because no elemental type is a single bit in most C++ environments, the individual elements are accessed as special references type (see bitset::reference ).
