Bitwise operators are used to perform operations on individual bits of the operand or operands. Each bit in the operand will be either 0 or 1. Bitwise operators in C are:
| Operator | Meaning |
|---|---|
| & | Bitwise AND; If both bits are 1 then result is 1 otherwise 0 |
| | | Bitwise OR; If either one of the bit is 1 then result is 1 otherwise 0 |
| ^ | Bitwise Exclusive OR (XOR); If only one bit (NOT BOTH) is 1 then result is 1 otherwise 0 |
| << | Left Shift; Moves the bit pattern to the left |
| >> | Right Shift; Moves the bit pattern to the right |
| ˜ | Complement; All 1 bits are changed to 0 and 0 bits are changed to 1 |
Consider two bit patterns
a = 0000 1100
b = 0000 0110| Operation | Meaning | Result |
|---|---|---|
| a & b | a AND b | 0000 0100 |
| a | b | a OR b | 0000 1110 |
| a ^ b | a XOR b | 0000 1010 |
| a << 2 | a Left Shift 2 | 0011 0000 |
| a >> 2 | a Right Shift 2 | 0000 0011 |
