The only difference between the while and the do while loop is that the condition in a while loop is evaluated before the code in the loop is run, where as it's evaluated afterwards in a do while loop. In other words, the code in a do while loop is guaranteed to run at least once. Otherwise, it's totally up to you which loop you want to use
