Question 4.4. (TCO 1) Which of the following statements is/are true? (Points : 5)

In object-oriented programming we design the program as a set of cooperating methods. The procedural paradigm permits the modeling of a software system in a more natural way compared to the object-oriented paradigm. Abstraction is the process of extracting the high level information about a category entity or activity, while ignoring the "unimportant" details. None of the above

Question 5.5. (TCO 1) Which of the following would be the most appropriate choice for a method in a Cube class? (Points : 5)

Volume() Area() Radius() CalculateVolume()

Question 6.6. (TCO 2) Which of the following statements is/are true? (Points : 5)

A. The state of an object must be public, for easier modification. B. A static method of a class can access non static members of the class directly. C. A constructor is automatically created for you if you do not define one. None of the above Only B and C

Question 7.7. (TCO 2) What parts of a class, designed as a black box system, should not be exposed to future programmers? (Points : 5)

Inputs Outputs Interface Implementation

Question 8.8. (TCO 2) Given a private attribute called species, which of the following are proper pseudocode implementations for a getter and a setter? (Points : 5)

void getSpecies(){return species} void setSpecies(string newSpecies){ species = newSpecies } string getSpecies (){return species } string setSpecies (string newSpecies){return newSpecies } string getSpecies (){species = newSpecies } void setSpecies (string newSpecies){return species } string getSpecies (){return species } void setSpecies (string newSpecies){ species = newSpecies}

Question 9.9. (TCO 2) You need to design an EntertainmentSystem class. How can you utilize the concept of encapsulation to design this class? (Points : 5)

Create at least one derived subclass of EntertainmentSystem which expands upon its functionality Create a Speaker class and a Screen class and integrate them into EntertainmentSystem using aggregation Design the class to include generic attributes and generic methods that are common to all EntertainmentSystem objects None of the above All of the above

Question 10.10. (TCO 7) Which of the following statements is false? (Points : 5)

A pure virtual function is a function without function implementation and can be found in an abstract class. If a derived class extends an abstract base class, the derived class must implement the pure virtual functions declared in the abstract base class. Any method in an abstract class is considered a pure virtual function. Pure virtual functions are inherited.

Question 11.11. (TCO 7) What is an abstract class? (Points : 5)

Any class which can be instantiated A class without any subclasses A conceptually vague or generalized class Any superclass with more than one subclass

Question 12.12. (TCO 7) In terms of object-oriented programming, rules for the use of an application programming interface or framework can be enforced through the use of a(n) _____. (Points : 5)
