Question

Write a program to accept a no. and check whether it is a Niven no. or not. Niven no. is that no. which is divisible by the sum of its digits.
Eg- 126 as 1+2+6=9 and 126 is divisible by 9

Answer 1

$check \: out \: code$

Answer 2

import java.util.*;

class niven_number

{

   public static void main(String args[])

   {

       Scanner sc=new Scanner(System.in);

       System.out.println("Enter a number to check whether it is a niven number or not");

       int n=sc.nextInt();

       int d=0;

       int s=0;

       int cpy=n;

       while(n>0)

       {

           d=n%10;

           s=s+d;

           n=n/10;

       }

       if(cpy%s==0)

       {

           System.out.println(cpy+" is a niven number");

       }

       else

       {

           System.out.println(cpy+" is not a niven number");

       }

   }

}
