If I delete a class, are its member variables automatically deleted?

Question

I have been researching, and nothing relevant has come up, so I came here.

I am trying to avoid memory leaks, so I am wondering:

Say I have class MyCla

Answer 1

When you free an object, all of its member variables are automatically freed as well. So, in your case, yes, a, b and c are all freed.

However, if one of your member variables is a pointer, only the pointer itself is automatically freed, not the object it points to - this is the most common case for having to write your own destructor.
