What is bitwise AND operator ?

The bitwise AND operator &|) is a bitwise logical operator. It is represent by ampersand (&) symbol. It works with two operands I.e. it is a binary operator. The comparison of bits started from the least significant bit. It works with operands bit by bit.

The result of bitwise AND operator is 1 when both bits has 1 values. other wise the result of bitwise AND operator is 0 (zero). It mainly used to test whether a particular bit 1 or 0 (zero). The operation table of bitwise  AND (&) operator is as follow:

Operand A	Operand B	Result ( A & B )
0	0	0
0	1	0
1	0	0
1	1	1

The precedence of bitwise AND operator is lower than the relational operator so additional parentheses are necessary.
