Test2(
True or false: The output of the function Test2() will always be "2, 6" when called.
True
Can a subclass inherit private methods from its superclass?
No
True or false: Private methods can be inherited by a subclass from its superclass.
False
Are private members visible outside of the unit or program where its class is declared?
No
True or false: Private members can be accessed and modified outside of the unit or program where its class is declared.
False
True or false: Public members are only visible within the same module where its class is declared.
False
Where are protected members visible?
Anywhere in the module where its class is declared and from any descendant class
What is encapsulation used for in object-oriented programming?
To bundle data and methods
True or false: Protected members are only visible from the same class where it is declared and from any descendant class.
False
True or false: Encapsulation is the process of hiding data and methods from other classes and modules.
True
What is a linked list?
A data structure that consists of a sequence of nodes
Does hierarchical classification rely on inheritance?
Yes
True or false: Linked lists can only be used to store integer data types.
False
What is a queue?
A data structure that consists of a sequence of nodes
True or false: Hierarchical classification is a feature of encapsulation.
False
What is the Enqueue operation?
Inserts an element at the end of the queue
True or false: A queue is a data structure that has three operations: Enqueue, Dequeue, and Front.
False
True or false: Inheritance is a way to create a new class by deriving from an existing class.
True
What is the Dequeue operation?
Removes an element from the beginning of the queue
True or false: A linked list is a linear data structure that can be used to implement stacks and queues.
True
Where are public members visible?
Anywhere its class can be referenced
Study Notes
- Inheritance is used to inherit properties from one class into another.
- The output of the function Test2() is "2, 6" when called.
- Private methods are not inherited by a subclass from its superclass.
- Private members are invisible outside of the unit or program where its class is declared.
- Public members are visible wherever its class can be referenced.
- Protected members are visible anywhere in the module where its class is declared and from any descendant class.
- Encapsulation is used to bundle data and methods that manipulate the data.
- Linked lists are a data type that consists of a sequence of nodes.
- Hierarchical classification is supported by inheritance.
- A queue is a data structure that has four operations: Enqueue, Dequeue, Front, and Isempty.
