[SOLVED]Please Explain me this code!

Question

this program works like this
1)Enter 2 digit eg 22
2) its add the 2 digits like
=》 22
=》2+2 =4
P.S. I got this code from my teacher can someone here can explain me this code.
import java.util.*;
class sum_digits
{
public static void main(String[] args)
{
Scanner sc=new Scanner(System.in);
System.out.println("Enter a number");
int n=sc.nextInt();
int s=0,x;
while(n!=0)
{
x=n%10;
s+=x;
n/=10;
}

Answer 1

When your while loop runs first:
x = 22%10 = 2
s += 2 = 2
n /= 10 = int 22/10 = 2
Now the value of x = 2, s = 2 and n = 2
When your while loop runs second:
x = 2%10 = 2
s += 2 = 2+2
n /= 10 = int 2/10 = 0
Now the value of x = 2, s = 4 and n = 0
And now your while loop will stop executing because n == 0, so the code stops.
Hope you will understand.

Answer 2

If the input is 27,
initially n = 27, s = 0. Here s is storing the sum.
The loop will run 🏃 until n is 0

Iteration 1:
x = 27%10 = 7
s = 0+7 = 7
n = 27/10 = 2

Iteration 2:
x = 2%10 = 2
s = 7+2 = 9
n = 2/10 = 0

Since n is 0 now, the loop will be stopped.

Answer 3

I was not able to understand the statements inside the while loop but now im Happy that i get a Good response thus now im able to understand the logic behind this complex code.
Thank you all For you Kindness ...
Appreciate your Efforts 😊😊

Answer 4

1 Scanner sc=new Scanner(System.in);
2 System.out.println("Enter a number");
3 int n=sc.nextInt();
4 int s=0,x;
5 while(n!=0)
6 {
7 x=n%10;
8 s+=x;
9 n/=10;
0 }
Line 1 declares a scanner to process input from the console
Line 2 displays a prompt to the console
Line 3 reads an integer from the console
Line 4 declares & zeros s and declares x
Line 5 tests n for zero, if 12 was entered n will be 12 the first time, 1 the second, and 0 the third
Line 7 sets x to the digit being removed by getting the ones column, it will be 2 the first time and 1 the second
Line 8 adds x to s making it 2 the first time and 3 the second
Line 9 gets the 10s column and beyond and replaces n with it, it will be 1 the first time and 0 the second.
Line 0 goes back to line 5

which part dont you understand?
