WebMar 7, 2024 · The bitwise arithmetic operator expressions have the form 1) bitwise NOT 2) bitwise AND 3) bitwise OR 4) bitwise XOR For the built-in operators, lhs and rhs must both have integral or unscoped enumeration type. Usual arithmetic conversions are performed on both operands and determine the type of the result.
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: WebAll of these operators are also available in C++, and many C-familylanguages.
