A common mistake with do-while loops is attempting to use a variable that is local to the loop in the conditional statement. This will result in a compilation error because the local variable is not in the correct scope for the conditional statement to use it. Be sure to declare any conditional variables outside of the do while loop. A common mistake with do-while loops is attempting to use a variable that is local to the loop in the conditional statement.
