WebIn normal scenario where a boolean memory reference points to the address of 1 byte in memory which contains either all zeros (for false) or all ones (for true), now to have 1 bit per boolean, you will point 8 booleans to the same byte, but you can't tell which bit inside this byte that gives you the value, so beside the normal memory reference, you will need a … WebApr 10, 2024 · Video. A Bitwise And operator is represented as ‘&’ and a logical operator is represented as ‘&&’. The following are some basic differences between the two operators. a) The logical and operator ‘&&’ expects its operands to be boolean expressions (either 1 or 0) and returns a boolean value.
