Question

• Ask user to input any 5-digit positive integer value. Calculate the sum of digits of that number.
  • Assume that the number is positive, integer, 5-digit.
  • Example: 29107 should calculate 2+9+1+0+7 and get 19
  • Hint: Use the % operator to extract a digit from a number.

Use loop(s)

Must be in Java

Answer 1

Java code:

import java.util.Scanner;
public class Main{
   public static void main(String[] args){
       Scanner input=new Scanner(System.in);
       //initializing number and sum
        int num,sum=0;
        //asking for number
        System.out.print("Enter a 5 digit positive integer: ");
        //accepting it
        num=input.nextInt();
        //looping for 5 iteration
        for(int i=0;i<5;i++){
            //adding last digit of number to sum
            sum+=num%10;
            //removing last digit from number
            num=num/10;
        }
        //printing the sum
        System.out.println("Sum="+sum);
   }
}
