It is the post-increment operator. It increases the value of the variable i by exactly 1.
Initialize the loop variable at the highest index (like array.length - 1), set the condition to i >= 0, and use i-- to decrement.
Yes. You can use i += 2 to skip every other element, or any mathematical operation like i *= 2 for exponential leaps.
