## Explanation

The provided C++ code demonstrates the use of various bitwise operators. The program begins by including the necessary header file `iostream`

and using the `std`

namespace to simplify the code.

```
#include <iostream>
using namespace std;
```

The `main`

function initializes two integer variables, `i`

and `j`

, with the values 15 and 22, respectively.

```
int i = 15; // First integer
int j = 22; // Second integer
```

The program then performs several bitwise operations on these integers and prints the results using `cout`

.

**Bitwise AND (**: This operation compares each bit of`&`

)`i`

and`j`

and returns a new integer where each bit is set to 1 only if both corresponding bits of`i`

and`j`

are 1. The result of`i & j`

is 6.

`cout << (i & j) << endl; // Expected output: 6`

**Bitwise OR (**: This operation compares each bit of`|`

)`i`

and`j`

and returns a new integer where each bit is set to 1 if at least one of the corresponding bits of`i`

or`j`

is 1. The result of`i | j`

is 31.

`cout << (i | j) << endl; // Expected output: 31`

**Bitwise XOR (**: This operation compares each bit of`^`

)`i`

and`j`

and returns a new integer where each bit is set to 1 if only one of the corresponding bits of`i`

or`j`

is 1. The result of`i ^ j`

is 25.

`cout << (i ^ j) << endl; // Expected output: 25`

**Bitwise NOT (**: This operation inverts all the bits of`~`

)`i`

, turning 1s into 0s and vice versa. The result of`~i`

is -16.

`cout << (~i) << endl; // Expected output: -16`

**Left Shift (**: This operation shifts the bits of`<<`

)`i`

to the left by 2 positions, effectively multiplying`i`

by 2^2 (or 4). The result of`i << 2`

is 60.

`cout << (i << 2) << endl; // Expected output: 60`

**Right Shift (**: This operation shifts the bits of`>>`

)`j`

to the right by 2 positions, effectively dividing`j`

by 2^2 (or 4). The result of`j >> 2`

is 5.

`cout << (j >> 2) << endl; // Expected output: 5`

Finally, the `main`

function returns 0, indicating that the program has executed successfully.

`return 0;`

This code provides a clear and concise demonstration of how bitwise operators work in C++, making it a useful reference for developers looking to understand these operations.
