This cheat sheet illustrates when/where one should use references,
const, pass-by-value, etc.
for some common (but of course not all) cases.
You should of course avoid direct access to class member variables, because you lose control over the interplay between this one member's state and the state of the other class members.

Parent (of type A) gets destroyed
and the destructor of one child (type B)
throws an exception ⇒ resources may leak!
Standard Library & Conventions Standard Library
