Question Question 24
Write a program to accept a number and check and display whether it is a Niven number or not. (Niven number number which is divisible by the sum of its digits).
Example:
Consider the number 126.
Sum of its digits is 1 + 2 + 6 = 9 and 126 is divisible by 9. Refer to Program 9.45 for the solution.
import java.util.Scanner;
public class KboatNivenNumber
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.print("Enter number: ");
int num = in.nextInt();
int orgNum = num;
int digitSum = 0;
while (num != 0) {
int digit = num % 10;
num /= 10;
digitSum += digit;
}
/*
* digitSum != 0 check prevents
* division by zero error for the
* case when users gives the number
* 0 as input
*/
if (digitSum != 0 && orgNum % digitSum == 0)
System.out.println(orgNum + " is a Niven number");
else
System.out.println(orgNum + " is not a Niven number");
}
}Output
