Bitwise Operators
The Bitwise operators supported by C language are listed in the following table. Assume variable A holds 60 and variable B holds 13 then:
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 either 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 effect of 'flipping' bits. |
(~A ) will give -61 which is 1100 0011 in 2's complement form due to a signed binary number. |
<< |
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 which is 0000 1111 |
