"WebFeb 22, 2024 · Defining bit masks in C++14 The simplest set of bit masks is to define one bit mask for each bit position. We use 0s to mask out the bits we don’t care about, and 1s to denote the bits we want modified. Although bit masks can be literals, they’re often defined as symbolic constants so they can be given a meaningful name and easily reused. " - Bitfield c

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 The smallest unit of memory that can be directly accessed with most contemporary hardware and programming languages is a byte or 8-bits. Bit-fields are built on the standard struct syntax and allow programmers to access units of memory smaller than a single byte.
