Hi Folks,

In K&B book Chapter-1, page -70 - the two minute drill section says - "Members accessed without the dot operator (.) must belong to the same class.".
At the same time there is an example in page 34, where a protected int x=9 variable in parent class is used in the child class without a dot operator.
I understand this is because of inheritance. then, what am missing with the statement in two-minute drill?

Thanks in Advance for your time folks.

I think a child class is also a type of its parent class.
A child class belongs to its parent class.
