![]() The above example refers to copying 32-bit data to a byte array. Source code that does bit manipulation makes use of the bitwise operations: AND, OR, XOR, NOT, and bit shifts.īit manipulation, in some cases, can obviate or reduce the need to loop over a data structure and can give many-fold speed-ups, as bit manipulations are processed in parallel, but the code can become more difficult to write and maintain. what is the difference between an array slice and part select. For most other tasks, modern programming languages allow the programmer to work directly with abstractions instead of bits that represent those abstractions. Computer programming tasks that require bit manipulation include low-level device control, error detection and correction algorithms, data compression, encryption algorithms, and optimization. Bit manipulation is the act of algorithmically manipulating bits or other pieces of data shorter than a word.
