C ++Program to sum the digits of a given number

This is a C ++Language example to calculate the sum of numbers,

Example

#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 result

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 to zero. The number is input by the user, and it will sum the number when the number is not equal to zero.

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