Bitwise operators perform operations on the individual bits of integer values. They are used for low-level programming tasks, such as controlling hardware, setting flags, and optimizing performance. Bitwise operators work directly on the binary (bit) representations of numbers.
| Operator | Description | Example |
|---|---|---|
& | Bitwise AND: Sets each bit to 1 if both bits are 1 | a & b |
| | Bitwise OR: Sets each bit to 1 if one of the bits is 1 | a | b |
^ | Bitwise XOR: Sets each bit to 1 if only one of the bits is 1 | a ^ b |
~ | Bitwise NOT: Inverts all the bits | ~a |
Below is an example that demonstrates how bitwise operators work using two integer values.
Explanation:
&):
0101 & 0011 results in 0001 (only the rightmost bit is 1 in both).1|):
0101 | 0011 results in 0111 (if either bit is 1, the result is 1).7^):
0101 ^ 0011 results in 0110 (bit is set to 1 only if the bits differ).6This example demonstrates how bitwise operators manipulate individual bits within integers. Experiment with these operators to understand how changing bits affects the outcome of expressions.
