WebDec 9, 2024 · 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. Such member is called a bit-field, and the number of bits associated with that field is (in bits, and not in bytes).

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. WebBit fields are allocated from a bit field container. The size of this container is determined by the declared type of the bit field. For example, a char bit field uses an 8-bit container, an int bit field uses 32 bits, and so on. The container must be large enough to contain the bit field, as the bit field will not be split across containers.
