C program to find the sum of ‘N’ natural numbers.

The natural numbers are the positive integers: 1, 2, 3, 4, 5, … Their sum from 1 to N can be computed two ways: a simple loop that adds each number, or the Gauss formula N×(N+1)/2 that gives the answer in O(1) time without any loop. This post shows both, explains why the formula works, …
