// CPP Program to Add Digits of a Number using Recursion #include <iostream> using namespace std; int add_digit(long int n) { int sum = 0; if (n == 0) { return n; } sum = add_digit(n / 10) + (n % 10); return sum; } int main() { long int n; cout << "Enter Number :--> "; cin >> n; int result = add_digit(n); cout << "The sum of the digits is : " << result; return 0; }
Output:
Enter Number :--> 654321
The sum of the digits is : 21
