A program to find the sum of "n" natural numbers (WHILE)

#include <stdio.h>
 
void main()
{
    int i = 1, sum = 0, n;
 
    printf("Enter a value for n: ");
    scanf("%d", &n);
 
    while (i <= n)
    {
        sum = sum + i;
        i++;
    }
    printf("Sum of %d natural numbers = %d", n, sum);
 
    printf("\n");
}
