# C# Bitwise Operator

In C#, bitwise operators are used to perform operations on the individual bits of integer values. The basic bitwise operators in C# are:

`&`

(bitwise AND)`|`

(bitwise OR)`^`

(bitwise XOR)`~`

(bitwise NOT)`<<`

(left shift)`>>`

(right shift)

Here are some examples of how to use bitwise operators in C#:

The `&`

operator performs a bitwise AND operation on the corresponding bits of its operands. The result is `1`

if both bits are `1`

, otherwise the result is `0`

.

The `|`

operator performs a bitwise OR operation on the corresponding bits of its operands. The result is `1`

if either bit is `1`

, otherwise the result is `0`

.

The `^`

operator performs a bitwise XOR (exclusive OR) operation on the corresponding bits of its operands. The result is `1`

if the corresponding bits are different, otherwise the result is `0`

.

The `~`

operator performs a bitwise NOT operation on its operand. This operator reverses the bits of the operand. If the operand is an `int`

, then the result is the two's complement representation of the negation of the operand.

The `<<`

operator performs a left shift operation on its first operand by the number of bits specified in its second operand. The left shift operation shifts the bits of the operand to the left, filling the empty spaces with zeros.

The `>>`

operator performs a right shift operation on its first operand by the number of bits specified in its second operand. The right shift operation shifts the bits of the operand to the right, filling the empty spaces with zeros or ones, depending on the sign of the operand.

Bitwise operators are used in low-level programming, such as device drivers and embedded systems, where the manipulation of individual bits is important. They can also be used in some algorithms, such as hashing and encryption.
