WebA bit-field is used to club together many variables into one object, similar to a structure. This allows for reduced memory usage and is especially useful in an embedded environment. e.g. consider the following variables having the ranges as given below. a --> range 0 - 3 b --> range 0 - 1 c --> range 0 - 7 d --> range 0 - 1 e --> range 0 - 1 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.
