I've knocked together a little solution which works with int's but i'm afraid 8790278573 doesnt fit in an int (on my computer at least). You can see the method i used anyway:

Code:

#include<iostream>

using namespace std;

int main() {

	int i = 790278573;  // Number you want to add the digits of

	int icopy = i;
	int result = 0;
        
	while(icopy > 0) {
		result += icopy % 10;
		icopy /= 10;
	}

	cout << "Initial number: " << i      << "\n";
	cout << "Sum of digits : " << result << "\n";
}

I'd like to see a better method if anyone would like to post one. I'm not that hot on C++

Hope this helps anyway
