What is bitwise OR operator ?

The bitwise OR operator (|) is a bitwise logical operator. It is represent by vertical bar (^) 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 OR operator is 0 (zero) when both bits has 0 (zero) values. The result of bitwise OR operator is 1 (one) when minimum one bit has the value 1. If both bits have value 1 than result is also 1. The operation table of bitwise  OR (|) operator is as follow:

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

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