See the variable definitions above to see why some of these are invalid. WebDec 9, 2024 · These fields are therefore known as bit-fields. These bit-fields are defined as members of a structure ( or union). C allows a structure to restrict its members to fewer number of bits. An unsigned or int member of a structure (or, union) can be declared to be made up of a specified number of bits.
