WebBitwise AND. Bitwise AND operator is represented by &. It performs bitwise AND operation on the corresponding bits of two operands. If either of the bits is 0, the result is 0. Otherwise the result is 1. If the operands are of type bool, the bitwise AND operation is equivalent to logical AND operation between them. WebIn the above program, 2 is assigned to a variable number.Then, the ternary operator is used to check if number is even or not..
