Bitwise Operators in C
I have seen bitwise operators in all programming language which I have used so far. Bitwise operators are used to do binary operation in the program. There are six bitwise operators in C programming language.
Now, let’s see the bitwise operators in c:
| Operator | Name | Description |
|---|---|---|
| & | AND | Sets each bit to 1 if both bits are 1 |
| | | OR | Sets each bit to 1 if one of two bits is 1 |
| ^ | XOR | Sets each bit to 1 if only one of two bits is 1 |
| ~ | NOT | Inverts all the bits |
| << | Zero fill left shift | Shift left by pushing zeros in from the right and let the leftmost bits fall off |
| >> | Signed right shift | Shift right by pushing copies of the leftmost bit in from the left, and let the rightmost bits fall off |
C example with bitwise operators:
m =10; /*"1010"*/
n =7; /*"0111"*/
printf("m AND n Operation: %d",m&n);/*0010=2*/
printf("m OR n Operation: %d",m|n);/*1111=15*/
printf("Before Left Shift Operation m: %d",m);/*1010*/
printf("After Left Shift Operation m: %d",(m<<2)&15);/*0100=8*/
Output:
m AND n Operation: 2 m OR n Operation: 15 Before Left Shift Operation m: 10 After Left Shift Operation m: 8
