No, the compiler allows it. However, it is considered bad practice because it makes the loop's behavior unpredictable and hard to debug.
If you increment the counter manually inside the loop, the loop's natural update step will increment it again, causing it to skip an element.
Yes. An unexpected double increment can push the counter past the bounds of an array, triggering an IndexOutOfBounds exception.
