If you're a C programmer, it'll help to think of classes as structs.
They're similar in many ways, including how to resolve their members.
Like structs, you can either have a class, or a pointer to class;
depends on your code.
You'd use foo.x() if 'foo' is a class, and
you'd use foo->x() if 'foo' is a /pointer/ to a class.
If you get it wrong and try to use . instead of ->
to resolve a pointer, you'll get those errors.
