Bitwise AND operator
expression & expression Bitwise and where the result contains a1ineach
bit position where there is a1inboth expressions and a0inallother bit
positions.

expression | expression Bitwise exclusive or where the result contains a 1
in each bit position where there is a1inonly one of the expressions and a
0 in all other bit positions.

position where there is a1ineither expression and a0inallother bit
positions.
