Bit fields are used when the storage of our program is limited. Need of bit fields in C programming language:
WebIn the C programming language, operations can be performed on a bit level using bitwise operators.. Bitwise operations are contrasted by byte-level operations which characterize the bitwise operators' logical counterparts, the AND, OR, NOT operators. Instead of performing on individual bits, byte-level operators perform on strings of eight bits (known as bytes) at … WebC Increment and Decrement Operators.
