Bitwise AND Operator
Bitwise AND Operator
The bitwise AND operator (&) performs a bitwise AND operation on its operands. This
operation is useful for bit manipulation.
Syntax
AND-expression ::=
equality-expression
AND-expression & equality-expression
Description
The result of the binary & operator is the bitwise AND function of the two operands. Both
operands must be integral types. The usual arithmetic conversions are performed on the
operands. The type of the result is the converted type of the operands. The result is not an
lvalue.
For each of the corresponding bits in the left operand, the right operand, and the result,
the following table indicates the result of a bitwise AND operation.
