"Web& Operator. The single AND operator (&) is known as the Bitwise AND operator. It operates on a single bit. It takes two operands. A bit in the result is 1 if and only if both of the corresponding bits in the operands are 1. The result of the operator may be any number. For example: a = 01100010. b = 10111010. a&b = 00100010 && Operator " - Bitwise-and operator
