Question

PLEASE HELP C++!!
Write a program with a recursive function to output the sum of the digits in a positive integer. Complete provided function prototype in your code, then use the provided driver program to test your code. You should get the same output. #include <iostream> using namespace std;
int addDigit (int n);
int main ( )
{
cout << "sum of the digits in the number 2017 is" << addDigit (2017)<< endl; cout << endl; return 0; }

Explanation / Answer

Answer:

C++ Code :

#include <iostream>
using namespace std;

int addDigit (int n);
int addDigit (int n)
{
if(n<=0)
return 0;
else
return (n%10) + addDigit(n/10);
  
}

int main ( )

{

cout << "sum of the digits in the number 2017 is " << addDigit (2017)<< endl;
cout << endl;
return 0;
}

Output :

sum of the digits in the number 2017 is 10
