    Study Notes

    1. Inheritance is used to inherit properties from one class into another.
    2. The output of the function Test2() is "2, 6" when called.
    3. Private methods are not inherited by a subclass from its superclass.
    4. Private members are invisible outside of the unit or program where its class is declared.
    5. Public members are visible wherever its class can be referenced.
    6. Protected members are visible anywhere in the module where its class is declared and from any descendant class.
    7. Encapsulation is used to bundle data and methods that manipulate the data.
    8. Linked lists are a data type that consists of a sequence of nodes.
    9. Hierarchical classification is supported by inheritance.
    10. A queue is a data structure that has four operations: Enqueue, Dequeue, Front, and Isempty.
