Why do we use row+1 step in preparation

As you already mentioned that one of the preparation steps includes printing ln i.e new line automatically the cursor will move to nxt line then why would you just add this row+1 statement despite the fact that it already has moved?

hey @stormborn
let row =1;
you are adding new line
but row will be remain same ,You will not get the desired output ( Will create an infinite loop )
