Bitwise operations in c++
WebBasically, you use them due to size and speed considerations. Bitwise operations are incredibly simple and thus usually faster than arithmetic operations. For example to get the green portion of an rgb value, the arithmetic approach is (rgb / 256) % 256. With bitwise operations you would do something as (rgb >> 8) & 0xFF. The latter is ...
