Bitwise Operators in C Programming
Introduction to Bitwise Operators in C Programming
Bitwise operators in C programming are used to perform operations directly on binary representations of data. These operators work at the bit level and are widely used in low-level programming, embedded systems, and performance optimization.
Understanding bitwise operators in C programming helps in writing efficient and optimized code.
What are Bitwise Operators in C Programming
Bitwise operators operate on individual bits of integers.
List of Bitwise Operators
Common Operators
&→ Bitwise AND|→ Bitwise OR^→ Bitwise XOR~→ Bitwise NOT<<→ Left Shift>>→ Right Shift
Bitwise AND Operator (&)
Returns 1 if both bits are 1.
int main() {
int a = 5, b = 3;
printf(“Result = %d”, a & b); // Output: 1
return 0;
}
Bitwise OR Operator (|)
Returns 1 if at least one bit is 1.
int main() {
int a = 5, b = 3;
printf(“Result = %d”, a | b); // Output: 7
return 0;
}
Bitwise XOR Operator (^)
Returns 1 if bits are different.
int main() {
int a = 5, b = 3;
printf(“Result = %d”, a ^ b); // Output: 6
return 0;
}
Bitwise NOT Operator (~)
Flips all bits.
int main() {
int a = 5;
printf(“Result = %d”, ~a);
return 0;
}
Left Shift Operator (<<)
Shifts bits to the left.
int main() {
int a = 5;
printf(“Result = %d”, a << 1); // Output: 10
return 0;
}
Right Shift Operator (>>)
Shifts bits to the right.
int main() {
int a = 5;
printf(“Result = %d”, a >> 1); // Output: 2
return 0;
}
Binary Representation Example
For better understanding:
- 5 → 0101
- 3 → 0011
Example
5 | 3 = 0111 (7)
5 ^ 3 = 0110 (6)
Practical Example: Check Even or Odd
int main() {
int num = 4;
if(num & 1)
printf(“Odd”);
else
printf(“Even”);
return 0;
}
