In this tutorial, we will be discussing a program to find sum of first n natural numbers.
For this we will be provided with an integer n. Our task is to add up, find the sum of the first n natural numbers and print it out.
#include<iostream> using namespace std; //returning sum of first n natural numbers int findSum(int n) { int sum = 0; for (int x=1; x<=n; x++) sum = sum + x; return sum; } int main() { int n = 5; cout << findSum(n); return 0; }
