Here we will discuss the problems related to series.

A number of related events or things following each other is called series.


Program to find the sum of n natural numbers.

#include<stdio.h>
int main()
{
    int n,s_n;
    printf("Enter the highest value of natural numbers you need to add\n");
    scanf("%d",&n);
    s_n = sumOfNaturalNumbers(n);
    printf("The sum %d natural numbers is equal to %d",n,s_n);
    return 0;
}

int sumOfNaturalNumbers(int k)
{
  k = k*(k+1)/2;
  return k;
}

output:

Enter the highest value of natural numbers you need to add
5
The sum 5 natural numbers is equal to 15
