# Bitwise Operations on Digits of a Number

Given a number N, the task is to perform the bitwise operations on digits of the given number N. The bitwise operations include:

• Finding the XOR of all digits of the given number N
• Finding the OR of all digits of the given number N
• Finding the AND of all digits of the given number N

Examples:

```Input: N = 486
Output:
XOR = 10
OR = 14
AND = 0

Input: N = 123456
Output:
XOR = 10
OR = 14
AND = 0```

Approach:

1. Get the number

2. Find the digits of the number and store it in an array for computation purpose.

3. Now perform the various bitwise operations (XOR, OR, and AND) on this array one by one.

Below is the implementation of the above approach:

## C++

 `// C++ implementation of the approach` `#include ``using` `namespace` `std;` `int` `digit[100000];` `// Function to find the digits``int` `findDigits(``int` `n)``{``    ``int` `count = 0;` `    ``while` `(n != 0) {` `        ``digit[count] = n % 10;``        ``n = n / 10;``        ``++count;``    ``}` `    ``return` `count;``}` `// Function to Find OR``// of all digits of a number``int` `OR_of_Digits(``int` `n, ``int` `count)``{` `    ``int` `ans = 0;` `    ``for` `(``int` `i = 0; i < count; i++) {``        ``// Find OR of all digits``        ``ans = ans | digit[i];``    ``}` `    ``// return OR of digits``    ``return` `ans;``}` `// Function to Find AND``// of all digits of a number``int` `AND_of_Digits(``int` `n, ``int` `count)``{` `    ``int` `ans = 0;` `    ``for` `(``int` `i = 0; i < count; i++) {``        ``// Find AND of all digits``        ``ans = ans & digit[i];``    ``}` `    ``// return AND of digits``    ``return` `ans;``}` `// Function to Find XOR``// of all digits of a number``int` `XOR_of_Digits(``int` `n, ``int` `count)``{` `    ``int` `ans = 0;` `    ``for` `(``int` `i = 0; i < count; i++) {``        ``// Find XOR of all digits``        ``ans = ans ^ digit[i];``    ``}` `    ``// return XOR of digits``    ``return` `ans;``}` `// Driver code``void` `bitwise_operation(``int` `N)``{` `    ``// Find and store all digits``    ``int` `countOfDigit = findDigits(N);` `    ``// Find XOR of digits``    ``cout << ``"XOR = "``         ``<< XOR_of_Digits(N, countOfDigit)``         ``<< endl;` `    ``// Find OR of digits``    ``cout << ``"OR = "``         ``<< OR_of_Digits(N, countOfDigit)``         ``<< endl;` `    ``// Find AND of digits``    ``cout << ``"AND = "``         ``<< AND_of_Digits(N, countOfDigit)``         ``<< endl;``}` `// Driver code``int` `main()``{` `    ``int` `N = 123456;` `    ``bitwise_operation(N);` `    ``return` `0;``}`
