  • The expression (a != b) and (a ^ b) are not equivalent. The != (not equal) operator checks if the values of two variables are different, while the ^ (bitwise XOR) operator performs a bitwise XOR operation on the binary representations of two values. Assume a = 25 (binary: 11001) and b = 30 (binary: 11110). 1. (a != b) would be true because 25 is not equal to 30. 2. (a ^ b) would be 7 because the bitwise XOR of 25 and 30 is 7 (binary: 00111).

    They are the same if a and b are booleans, as specified in the question. Commented Jan 4, 2024 at 17:52
