Question 8.8. (TCO 2) A class is designed with three public attributes: attributeOne, attributeTwo and attributeThree. attributeOne is an integer data type, attributeTwo is a double data type and attributeThree is a string data type. Which pseudocode representation(s) of getters would be appropriate for this class? (Points : 5)        int getAttributeOne()
      {
return attributeOne
      }
       string getAttributeTwo()
      {
return attributeTwo
      }
       int getAttributeThree(int newAttributeThree)
      {
attributeThree = newAttributeThree
}
       void getAttributeTwo()
      {
return attributeOne
}
       Both A and D
       None of the above Question 9.9. (TCO 2) You are tasked to create an EntertainmentSystem class and you want to minimize data dependencies. You also need to protect specific attributes from outside entities. What object-oriented concept(s) would you use to accomplish these goals? (Points : 5)        Composition of classes
       Universal access to methods
       Inheritance
       Encapsulation
       All of the above Question 10.10. (TCO 7) Which of the following statements is true? (Points : 5)        A pure virtual function is a function without function implementation and is ended with =0;
       An actual object can be created from an abstract class.
       A pure virtual function is a function that cannot be inherited and therefore must be overloaded.
       A pure virtual function cannot be overridden. Question 11.11. (TCO 7) A(n) _____ cannot be instantiated and therefore is used only to form related derived classes. (Points : 5)        method
       abstract method
       class
       abstract class Question 12.12. (TCO 7) _____ enforce a(n) _____ which is a methodology used in object-oriented programming to forces programmers to adhere to certain "rules."(Points : 5)        Abstract classes; contract
       Static variables; hierarchy
       Classes; transitive communication
       Method signatures; encapsulation

       None of the above

Explanation / Answer

8.attributeThree is a string data type. must be used because for you need to encapsulate some fields

9   Encapsulation because encapsulation used for binding of data and for data protections

10 A pure virtual function is a function without function implementation and is ended with =0; //it starts with virtual

11  abstract class it can not be instantiated

12  Method signatures; encapsulation .  encapsulation always has  accessors and mutators which are returned to the object state .
