C++ language was horrible with pointers allowing people to write code that didn't do what they expected it to do.  The basic abstract OO concept that your variable is now a container which may have other variables inside it as well as methods to execute some code should be easy.  The trickier part would be recognizing that an instance variable is not an object but a pointer to that object, so if you pass an object variable into a method you get 2 pointers to the same container, and I did write one memory leak myself, keeping links to objects using private variables in other objects so I was unable to access the linked objects myself and they were unable to be garbage collected.
