There will be an array of elements. Add each digit of element and print the sum of each element.    
Input:
32
11
Expected Output:
5
2
I am getting output as 7. How can i solve this?  


What I have tried:

Java
import java.util.Scanner;

public class Main

{

    public static void main(String args[])

    {

        int n, sum = 0;

        Scanner sc = new Scanner(System.in);
        int size=sc.nextInt();
        System.out.print("Enter the number:");
        int a[]= new int[size];
        for(int i=0;i<size;i++)
        {
            a[i]=sc.nextInt();
        }
        for(int i=0;i<size;i++)
        {
         for(int j=0;j<size;j++)
         {
        while(a[j] > 0)

        {

            n = a[j] % 10;

            sum = sum + n;

            a[j] = a[j] / 10;


        }
         }

        }

        System.out.println("Sum of Digits:"+sum);
        }
}

import java.util.Scanner;

public class SumD {
public static void main(String[] args) {
int n;
int sum=0;
Scanner sc=new Scanner(System.in);
int size=sc.nextInt();
int ar[]=new int[size];
for (int i = 0; i < ar.length; i++) {
ar[i]=sc.nextInt();
}
for (int i = 0; i < ar.length; i++) {
for (int j = 0; j <= i; j++) {
while (ar[j]>0) {
n=ar[j]%10;
sum=sum+n;
ar[j]=ar[j]/10;
}
}
System.out.println(sum);
sum=0;
}
}
}
//this is another solution to what i have given below

This is just a simpler version of your previous question:
Sum of a digit at even and odd places in an array[^]

Think about the logical steps you need to perform:
- read the next number
- set the sum to zero
- calculate the sum of the digits in the input number
- print the sum
- repeat for the next input

Your actual output is the sum of expected output.
Just a guess:
- you print result in wrong place.
- you forgot to reset the sum to 0.

Advice: Learn to indent properly your code, it show its structure and it helps reading and understanding. It also helps spotting structures mistakes.
C++
import java.util.Scanner;
public class Main
{
    public static void main(String args[])
    {
        int n, sum = 0;

        Scanner sc = new Scanner(System.in);
        int size=sc.nextInt();
        System.out.print("Enter the number:");
        int a[]= new int[size];
        for(int i=0;i<size;i++)
        {
            a[i]=sc.nextInt();
        }
        for(int i=0;i<size;i++)
        {
            for(int j=0;j<size;j++)
            {
                while(a[j] > 0)
                {
                    n = a[j] % 10;
                    sum = sum + n;
                    a[j] = a[j] / 10;
                }
            }
        }
        System.out.println("Sum of Digits:"+sum); // wrong place
    }
}
