## Introduction to C Bitwise Operators

Bitwise operators are used to perform operations on the bits of a binary number. They are used in a variety of applications, such as data encryption, image processing, and networking.

## Bitwise Operators in C

C has the following bitwise operators:

`&`

(bitwise AND)`|`

(bitwise OR)`^`

(bitwise XOR)`~`

(bitwise NOT)`<<`

(left shift)`>>`

(right shift)

## Bitwise AND Operator

The bitwise AND operator (`&`

) copies a bit to the result if it exists in both operands. For example, the expression `1 & 2`

will evaluate to 0, because only the leftmost bit of both operands is 1.

## Bitwise OR Operator

The bitwise OR operator (`|`

) copies a bit to the result if it exists in either operand. For example, the expression `1 | 2`

will evaluate to 3, because the leftmost bit of both operands is 1, and the rightmost bit of the second operand is 1.

## Bitwise XOR Operator

The bitwise XOR operator (`^`

) copies a bit to the result if it is set in one operand but not both. For example, the expression `1 ^ 2`

will evaluate to 3, because the leftmost bit of the first operand is 1, and the leftmost bit of the second operand is 0.

## Bitwise NOT Operator

The bitwise NOT operator (`~`

) flips all the bits in a binary number. For example, the expression `~1`

will evaluate to -2, because the binary representation of -2 is 10000001 in two’s complement notation.

## Bitwise Left Shift Operator

The bitwise left shift operator (`<<`

) shifts the bits in a binary number to the left by a specified number of places. For example, the expression `1 << 2`

will evaluate to 4, because the binary representation of 4 is 00000100 in two’s complement notation.

## Bitwise Right Shift Operator

The bitwise right shift operator (`>>``) shifts the bits in a binary number to the right by a specified number of places. For example, the expression`

1 >> 2` will evaluate to 0, because the binary representation of 0 is 00000000 in two’s complement notation.

## Bitwise Operators Examples

Here are some examples of how bitwise operators are used in C:

## Conclusion

Bitwise operators are a powerful tool that can be used to perform a variety of tasks in C. By understanding how they work, you can write more concise and efficient code.
