For operations 5&3, the output is 1, as the AND operation between 101 and 011 gives the value 001, which is a binary of 1. For an operation 5 3, …
WebThe Bitwise AND operator (&) is a binary operator which takes two bit patterns of equal length and performs the logical AND operation on each pair of corresponding bits. It returns 1 if both bits at the same position are 1, else returns 0. The example below describes how bitwise AND operator works: 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.
