Bitwise Operators
1. Bitwise Operators are used for operating numbers at the bit level.
2. There are following Bitwise operators supported by C language:
| Operators | What They Do .. | Precedence |
|---|---|---|
| ~ | This operator gives the NOT for every bit of the character. Also , this is followed : ~x = -x - 1. | 1 |
| << | It shifts the bits to the left , accordingly. | 2 |
| >> | Similar operation , but to the right. | 2 |
| & | This operator performs the AND logical operation on every corresponding bit of characters , and gives cumulative result of each bit as the result. | 3 |
| | | Similar , but performs OR operation on each bit. | 4 |
| ^ | Similar , but performs XOR operation on each bit. | 5 |
Syntax for Bitwise NOT (~):
~[variable\constant]
Example:~5
Syntax for all other Bitwise Operators:
[variable\constant] [Bitwise Operator] [variable\constant]
Example:(A ^ B)
C Example
#include<stdio.h>
int main() {
int a,b,c,d,e,f,g,h;
a=10;
b=11;
c=~a;
// Bitwise NOT
d=b<<2;
// Bitwise LEFT SHIFT
e=a>>2;
// Bitwise RIGHT SHIFT
f=a&b;
// Bitwise AND
g=a|b;
// Bitwise OR
h=a^b;
// Bitwise XOR
printf("a=%d,b= %d",a,b);
printf("c=%d,d= %d,e=%d,f= %d,g=%d,h=%d,",c,d,e,f,g,h);
return 0;
}
