. :: ->

Question

When using c++ classes, when do I use the dot(.) double colon (::) and the arrow (->)?

Answer 1

The dot is for accessing members of an object.

The double colon is to access a class' member or a namespace's

Finally the arrow is to access an object's member from a pointer.

my_personj.setName("something");

person_ptr->printName();

Person::myMethod();
