C's bitwise operators work on the bits stored in integral types. They work similar to the logical operators except that instead of working on true and false values they work with ones and zeroes. There are several bitwise operators available:
Symbol Meaning
~ Complement
& And
 Or
^ ExclusiveOr
<< Left shift
>> Right shift
The complement operator is a unary operator.
The other bitwise operators are binary, taking two operands.
Bitwise operator works on bits and perform bit by bit operation.
Assume if A = 60; and B = 13; Now in binary format they will be as follows:
A = 0011 1100
B = 0000 1101

A&B = 0000 1100
AB = 0011 1101
A^B = 0011 0001
~A = 1100 0011
The Bitwise operators supported by C language are
Operator

Description

Example

&

Binary AND Operator
copies a bit to the result if it exists in both operands.

(A & B) will give 12
which is 0000 1100



Binary OR Operator copies
a bit if it exists in eather operand.

(A  B) will give 61
which is 0011 1101

^

Binary XOR Operator
copies the bit if it is set in one operand but not both.

(A ^ B) will give 49
which is 0011 0001

~

Binary Ones Complement
Operator is unary and has the efect of 'flipping' bits.

(~A ) will give 60 which
is 1100 0011

<<

Binary Left Shift
Operator. The left operands value is moved left by the number of bits
specified by the right operand.

A << 2 will give
240 which is 1111 0000

>>

Binary Right Shift
Operator. The left operands value is moved right by the number of bits
specified by the right operand.

A >> 2 will give 15
