(TCO 2) You need to design an Automobile class. How can you utilize the concept of encapsulation to design this class?

Subdivide the two most general attributes of any Automobile, make and model, into more specific attributes.

Create a Make class and a Model class and integrate them into Automobile using composition.

Find a Transportation class and inherit everything you need from it

All of the above

Question 8

(TCO 2) You need to utilize an Item class in your own object-oriented class using composition. Luckily, one of your fellow students just finished writing their own version of an Item class. If the Item class was properly designed as a(n) _____, you do not need to know the specific details of how the class was implemented. Instead, you only need to become familiar with its _____.

abstract class; abstract methods

object-oriented instance; method implementations

black box system; interface

interface; inheritance hierarchy

Question 9

(TCO 2) A class is designed with two public attributes: attributeOne and attributeTwo. attributeOne is an integer data type while attributeTwo is a string data type. Which pseudocode representation(s) of setters would be appropriate for this class?

int setAttributeOne(int newAttributeOne)
      {
return attributeOne
      }

void setAttributeOne(int newAttributeOne)
      {
attributeOne = newAttributeOne
      }

string setAttributeTwo (int newAttributeTwo)
      {
attributeTwo = newAttributeTwo
}

void setAttributeTwo ()
      {
attributeTwo = " "
}

Both A and C

None of the above

Question 10
5 pts
(TCO 7) Which of the following statements is false?

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.
