WebTo perform bit-level operations in C programming, bitwise operators are used. Bitwise AND Operator & The output of bitwise AND is 1 if the corresponding bits of two operands is 1. If either bit of an operand is 0, the result of corresponding bit is evaluated to 0. In C Programming, the bitwise AND operator is denoted by &.
