Answer
Incorrectly initializing or updating the counter.
Common mistakes include starting the counter at the wrong index or forgetting to update it. For instance, starting at 1 instead of 0 in an array, or failing to increment the counter, can lead to errors or infinite loops. Example: for(int i = 0; i < cartItems.length; i++) { total += cartItems[i].price; }.
