Quiz questions

Write a program that asks the user quiz questions. You can keep the interface simple, because it is (of course) all about the data model in this assignment. You will implement several types of quiz questions, each of which must be called in the same way.

The task is to create the (abstract) class Question and its subclasses. The following types of questions are possible in the program:

• ChoiceQuestion - A question with multiple answers of which only 1 is correct.
• NumericalQuestion - A mathematical question where you have to enter the correct answer (as int).
• TrueFalseQuestion - A question where the answer consists of ‘true’ or ‘false’.

A few tips to get you started:

• Start by modelling a Question where you should think about how the question text is retrieved and how the answer can be checked.
• Keep the result as simple as possible, in our solution, we have chosen for all answers to be based of type int.
• A Question should be able to show the question text and is able to check the answer, similarly to what you did a few weeks ago.
• A Quiz class could be useful to manage the actual game aspect of the exercise.
