WebA bit wise NOT (unary complement) operates on the bit level and simply flips each bit. If it's a 1, it's changed to a 0, if it's a 0, it's changed to a 1. The bit wise NOT has the same effect as XOR'ing a value against the max value for a specific type: WebSep 28, 2024 · Here is an example of the bitwise OR used in a snippet of C++ code: 1 int a = 92; 2 int b = 101; 3 int c = a b; Bitwise OR is often used to make sure that a given bit is turned on (set to 1) in a given expression. For example, to copy the bits from a into b , while making sure the lowest bit is set to 1, use the following code: 1 b = a 1;
