## Example

Live Demo

#include<iostream>
using namespace std;
int main() {
int x, s = 0;
cout << "Enter the number : ";
cin >> x;
while (x != 0) {
s = s + x % 10;
x = x / 10;
}
cout << "\nThe sum of the digits : "<< s;
}

## Output

Enter the number : 236214828
The sum of the digits : 36

In the above program, two variables x and s are declared and s is initialized with zero. The number is entered by the user and when number is not equal to zero, it will sum up the digits of number.

while (x != 0) {
s = s + x % 10;
x = x / 10;
}
