Answer 1

Required Answer:-

Question:

• Write a program to accept a number and print the sum of digits and the number of digits present in it.

Solution:

Here comes the program.

import java.util.*;

public class Number {

 public static void main(String[] args) {

     int n,c=0,s=0;

     Scanner sc=new Scanner(System.in);

     System.out.print("Enter a number: ");

     n=sc.nextInt();

     while(n!=0) {

       s+=n%10;

       c++;

       n/=10;

     }

     System.out.println("Sum of digits: "+s);

     System.out.println("Number of digits: "+c);

     sc.close();

 }

}

Algorithm:

1. START
2. Accept the number.
3. Initialise count = 0, sum = 0
4. Divide the number till the number is not zero.
5. Increment the value of count.
6. Add the remainder to sum variable when the number is divided by 10.
7. Display the sum and number of digits.
8. STOP.
