1) This code is intended to count the number of digits in an integer input by the user. However, it has a logical error that causes an infinite loop. 2) Hint 1: The variable `n` never changes inside the loop, so the condition `n != 0` will always be true. Hint 2: To count digits correctly, you need to modify `n` inside the loop (e.g., by dividing it by 10).
