Teaching Tips

Some students may have already heard how difficult it can be to work with pointers.  Although this can be the case if one doesn't know what they are doing, if a programmer keeps in mind the two main points stressed in the notes (pointers contain addresses and keeping straight whether the program is dealing with the pointer or what the pointer points to) then they should find that pointers aren't as difficult as they might have heard.
