In this video we discuss about what is sum of first N natural number in c programming language.

hello friends , I'm piyush and welcome to our youtube channel type of gyan.
about our video-
This C program allows the user to enter any integer value. By using the For loop, this C program calculates the sum of N natural numbers.
The concept of finding the sum of sum of integers is found such that first, we will find the sum of numbers up to n and then add all the sums to get a value which will be the sum of sum which is our desired sum.

For this problem, we are given a number n up to which we have to find the sum of the sum. Let's take an example to find this sum.

n = 4
Now we will find the sum of numbers for every number from 1 to 4 :

Sum of numbers till 1 = 1
Sum of numbers till 2 = 1 + 2 = 3
Sum of numbers till 3 = 1 + 2 + 3 = 6
Sum of numbers till 4 = 1 + 2 + 3 + 4 = 10
Now we will find the sum of sum of numbers til n :
Sum = 1+3+6+10 = 20
