         * Exercise 2
         * a) Re-Create the Trivia Game from before. This time with 5 questions & 5 answers.
         *  Use arrays to save the question and answers.
         *  Create at least two methods that make the code more readable and easier to follow.
         *  --> HINT: Duplicate code can usually be made into methods
         * BONUS: Use and endless while loop with if statements so the user can play until they
         *        don't want to anymore.
