C PROGRAM TO FIND THE SUM OF FIRST N NATURAL NUMBERS

We will use for loop to find the sum of first n natural numbers.

#include <stdio.h>

int main()

{

    int n, count, sum = 0;

    printf("Enter the value of n(positive integer): ");

    scanf("%d",&n);

    for(count=1; count <= n; count++)

    {

        sum = sum + count;

    }

    printf("Sum of first %d natural numbers is: %d",n, sum);

    getch();

}
