Pointers always take more than just a good read to really grasp. So try not to get too frustrated when you start getting unpredictable errors/results.

Also, it would probably be a good idea to learn about smart-pointers shortly after getting the hang of pointers. It is considered good practice to use them in a lot of cases now. Although that could just add to the confusion.

And I would also highly suggest learning how to learn from a book. It is a very important skill, especially if you are planning on programming (or anything really) as a career.

If I were you, I'd pick up a good C++ book and read it front-to-back. (back-to-front would be a bit harder.)
