Bit-Wise operators

‘C’ has distinction of supporting special operators known as bit-wise operators for manipulation of date at bit level.

These operators are used for testing the bits or shifting them right or left.

Bit-wise operator may not be applying to float or double.

Operator	Meaning
&	Bit-wise AND
|	Bit-wise OR
^	Bt-wise Exclusive (or) XOR Operator
<<	Shift left
>>	Shift right
~	Bit-wise NOT (or) Complement

Bit-wise AND :-

Two variables x & y whose values are 10 & 15 respectively.
Calculate Z=X & Y.

Bit-wise AND

X=10          -  0000  0000  0000  1010 Y=15          -  0000  0000  0000  1111

Z=X&Y          -  0000  0000  0000  1010  =  10

Bit-wise OR:-

Calculate Z=X|Y

Bit-wise OR

X=10          -  0000  0000  0000  1010 Y=15          -  0000  0000  0000  1111

Z=X|Y         -  0000  0000  0000  1111  =  15

Bit-wise XOR:-

Calculate Z=X^Y

Bit-wise Ex-OR (XOR)

X=10          -  0000  0000  0000  1010 Y=15          -  0000  0000  0000  1111

Z=X^Y          -  0000  0000  0000  0101  =  5

Bit-wise Left Shift:-

If x=10, calculate x<<3.

Bit-wise Left Shift

X=10           -  0000  0000  0000  1010

Z=X<<3       -  0000  0000  0101  0000  =2*2*2*2 + 2*2*2*2*2*2                                                   = 16 +64=80

Bit-wise Right Shift:-

If x=10, calculate x>>3.

Bit-wise  Right Shift

X=10            -  0000  0000  0000  1010

Z=X>>3            -  0000  0000  0000  0001  =1

Y=15            -  0000  0000  0000  1111

Z=Y>>3            -  0000  0000  0000  0001  =1

Bit-wise complement:-

Unary operator & inverts all the bits represented by its variables. That is 0’s becomes 1’s & 1’s becomes 0’s.

Bit-wise Complement

X=10            -  0000  0000  0000  1010

Z=X<<3            -  0000  0000  0000  0101  =5
