Use the bitwise operators to modify the individual bits of numerical operands.

Bitwise operators associate from left to right. The only exception is the bitwise com-
plement operator not which associates from right to left.

The bitwise operators 

and, or,

and 

xor

perform logical operations on the appro-

priate pairs of bits of their operands. The operator 

not

complements each bit of its

operand. For example:

and

bitwise AND; compares pairs of bits and generates a 1 result if both
bits are 1, otherwise it returns 0

or

bitwise (inclusive) OR; compares pairs of bits and generates a 1 result
if either or both bits are 1, otherwise it returns 0

xor

bitwise exclusive OR (XOR); compares pairs of bits and generates a 1
result if the bits are complementary, otherwise it returns 0

not

bitwise complement (unary); inverts each bit

<<

bitwise shift left; moves the bits to the left, it discards the far left bit
and assigns 0 to the right most bit.

>>

bitwise shift right; moves the bits to the right, discards the far right bit
and if unsigned assigns 0 to the left most bit, otherwise sign extends
