WebAt a deep level, your computer works with bits— 1 s and 0 s. But these get bundled up into more human readable things, like characters and array s. This is called abstraction. While abstractions are nice, sometimes we want to work directly with bits. You can do this with bit manipulation, which involves bitwise operations.

WebAug 29, 2024 · A mask defines which bits you want to keep, and which bits you want to clear. Masking is the act of applying a mask to a value. This is accomplished by doing: Below is an example of extracting a subset of the bits in the value: Applying the mask to the value means that we want to clear the first (higher) 4 bits, and keep the last (lower) 4 bits.
