WebIn programming terminology, a bit field is a data structure that allows the programmer to allocate memory to structures and unions in bits in order to utilize computer memory in an efficient manner. Since structures and unions are user-defined data types in C, the user has an idea of how much memory will they occupy. WebA bit field declaration is a struct or union member declaration which uses the following declarator : a name of the bit field that is being declared. The name is optional: nameless bit fields introduce the specified number of bits of padding. an integer constant expression with a value greater or equal to zero and less or equal the number of ...
