__ Write a function that return sum of all the odd digits of a given positive no entered through keyboard in c++__

Given a number , write a function that return sum of all the odd digits of a given positive no entered through keyboard in c++ .

### Sample input

4567

### Sample Output:

Sum of odd digits of 4567 is: 12

__ Write a function that return sum of all the odd digits of a given positive no entered through keyboard in c++__

The objective of the code is to write a function that return sum of all the odd digits of a given positive number entered by the user .

__Algorithm:-__

- Define a function called
`sumOddDigits`

which takes a positive integer as its argument. - Initialize a variable called
`sum`

to zero. - While the given positive integer is greater than zero:
a. Extract the last digit of the integer using the modulus operator (%).
b. Check if the extracted digit is odd or not using the modulus operator (%).
c. If the digit is odd, add it to the
`sum`

variable. d. Divide the integer by 10 to remove the last digit. - Return the final
`sum`

variable.

__Code(C++):-__

#include <iostream>

using namespace std;

int sumOddDigits(int n) {

int sum = 0;

while (n > 0) {

int digit = n % 10;

if (digit % 2 != 0) {

sum += digit;

}

n /= 10;

}

return sum;

}

int main() {

int num;

cout << "Enter a positive integer: ";

cin >> num;

cout << "Sum of odd digits of " << num << " is: " << sumOddDigits(num) << endl;

return 0;

}

__Output:-__

Enter a positive integer: 4567

Sum of odd digits of 4567 is: 12
