Question: What is the `.*` operator and what does it do?

1. It is the same as the class member access operator, or arrow operator `(->)`, which allows you to access a member of an object through a pointer to the object.
2. It is the pointer to member operator, and it allows you to access a member of an object through a pointer to that specific class member.
3. It is the member access with address of operator, which returns the address of a class or struct member.
4. It is a combination of the member access operator `(.)` and the dereference operator `(*)`, so it allows you to access the object that a member pointer points to.
