You use pre-decrement if you want to decrement the variable before the value is passed on to the remaining expression. On the other hand, a post-decrement evaluates the expression before the variable is decremented.
You should have ++i; (not that it matters), and should have tempCounter-- Otherwise you will miss the "first" index of charArr.
