feat: add exercise for pointer concept
@siebenschlaefer Thanks for all the feedback, you were completely right. This one was hard and it took me quite a while to get back into the exercise game. The windowing java thing was not the right fit for cpp pointers. I scraped everything and created a completely new exercise, it is more limited in range and probably more direct to help students understand the concepts.
@ahans You are very welcome to comment :raised_hands:
I added a task, so students can use the & opertor.
Hey @ErikSchierboom, do you have time to review this new exercise? I would like to move the syllabus along, but the other two maintainers seem busy.
