3. Bitwise Operator
Bitwise operator permit programmer to access and manipulate
of data at bit level.
Various bitwise operator enlisted are
• One's complement (~)
• Bitwise AND (&)
• Bitwise OR (|)
• Bitwise XOR (^)
• Left shift (<<)
• Right shift (>>)
These operator can operate on integer and character value but
not on float and double.

9. Bitwise Operator

10. 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
A|B = 0011 1101
A^B = 0011 0001
~A = 1100 0011
A<<2 = 1111 0000
A>>2 = 0000 1111
Bitwise Operator (Example)

11. main()
{
unsigned int a = 60; /* 60 = 0011 1100 */
unsigned int b = 13; /* 13 = 0000 1101 */
int c = 0;
c = a & b; printf("Line 1 - Value of c is %dn", c );
c = a | b; printf("Line 2 - Value of c is %dn", c );
c = a ^ b; printf("Line 3 - Value of c is %dn", c );
c = ~a; printf("Line 4 - Value of c is %dn", c );
c = a << 2; printf("Line 5 - Value of c is %dn", c );
c = a >> 2; printf("Line 6 - Value of c is %dn", c );
}
