This implies that all the integer types could be 16 bits wide, which is incorrect. The requirements are that: - 'char' must hold at least 8 bits - 'short' must hold at least 16 bits - 'int' must hold at least 16 bits - 'long' must hold at least 32 bits - 'float' must hold at least 6 (decimal) digits - 'double' must hold at least 10 (decimal) digits The ISO C++ requirements are borrowed from the ISO C requirements, in ANSI/ISO 9899-1990, 5.2.4.2. -- David R.
