## C++ program to calculate sum of all natural numbers using recursion

#include<iostream> using namespace std; int getSum(int N); int main() { int n; cout << "Enter an Integer\n"; cin >> n; cout << "Sum of Numbers from 1 to " << n << " = " << getSum(n); return 0; } int getSum(int N) { if(N >= 1) return N + getSum(N-1); else return 0; }Output

Enter an Integer 10 Sum of Numbers from 1 to 10 = 55
