WebThe following table lists the Bitwise operators supported by C. Assume variable 'A' holds 60 and variable 'B' holds 13, then −. Binary AND Operator copies a bit to the result if it exists in both operands. Binary OR Operator copies a bit if it exists in either operand. Binary XOR Operator copies the bit if it is set in one operand but not both. WebAll data is stored in its binary representation. The logical operators, and C language, use 1 to represent true and 0 to represent false. The logical operators compare bits in two numbers and return true or false, 1 or 0, for each bit compared. Bitwise AND operator & The output of bitwise AND is 1 if the corresponding bits of two operands is 1.
