Bitwise AND Operator

The bitwise AND operator (&) returns the bitwise AND of the two operands. All bits that are on (1) in both the left and right operand are on in the result; bits that are off (0) in either the left or the right operand are off in the result.

Syntax

and-expression :

relational-expression
and-expression & equality-expression

Both operands to the bitwise AND operator must be of integral types. The usual arithmetic conversions covered in Arithmetic Conversions in Chapter 3, are applied to the operands.
