//Program to find sum of first n (entered by user) natural numbers

import java.util.Scanner;

public class abc {

    public static void main(String[] args) {

        int num, count, tot = 0;

        System.out.println("Enter the value of n:");

        //Scanner is used for reading user input

        Scanner scan = new Scanner(System.in);

        //nextInt() method reads integer entered by user

        num = scan.nextInt();

        //closing scanner after use

        scan.close();

        for(count = 1; count <= num; count++){

            tot = tot + count;

        }







        System.out.println("Sum of first "+num+" natural numbers is: "+tot);

    }

}



Output:-

Enter the value of n:

5

Sum of first 5 natural numbers is: 15
