44)   Write a program to input a number and find the Sum and Count the all digit of this number.  (2784=2+7+8+4=21…no. of digit=4)

import java.util.*;

public class sum_count_digits

{

   public static void main(String args[ ])

   {

      Scanner sc = new Scanner (System.in);

      System.out.println("Enter a number");

      int a = sc.nextInt();

      int c = 0;

      int s = 0;

      while(a>0)

      {

          int d = a%10;

          c++;

          s=s+d;

          a=a/10;

      }

      System.out.println("SUM of all digits of a entered number = "+s);

      System.out.println("Number of digits in a entered number = "+c);

    }

}

 

 Output : 

sum-of-all-digits-of-a-number
