ICSE 2016 Question 8 solution
Write a program to accept a number and check and display whether it is
a Niven number or not.
(Niven number is the number which is divisible by its sum of digits it
is also called Harshad number)
Example:
Consider the number 126
Sum of its digits is 1 + 2 + 6 = 9 and 126 is divisible by 9
Solution:
import java.util.*;
/**
* class Niven Or Harshad Number
* @author (Khurshid Md Anwar)
*/
public class NivenOrHarshadNumber
{
public static void
main(String args[])
{
int n, s, a, p;
Scanner sc = new
Scanner(System.in);
System.out.print("Enter a number : ");
n = sc.nextInt(); // take the number
p = n;
s=0; // initialize s for summation
as 0
while(n!=0)
{
a = n % 10; // mod division for reminder
s = s + a; // sum the reminder
n = n / 10; // integer division
}
// check the summation
whether it is divisble by entered number
// or not
if(p % s == 0)
{
System.out.println("It
is a Niven / Harshad Number");
}
else
{
System.out.println("It is not a Niven / Harshad Number");
}
}
}
Output:
Enter a number : 126
It is a Niven / Harshad Number
Enter a number : 125
It is not a Niven / Harshad Number
