Question

Question 1.1. (TCO 4) Which of the following is true about inheritance? (Points : 5)        Child classes are more generalized than their associated parent classes
       Parent classes are more specialized than their associated child classes
       Parent classes contain more functionality than child classes
       Inheritance demonstrates the generalization/specialization relationship Question 2.2. (TCO 4) There are two classes: class GeometricObject and class Cylinder. Which one is the base class and which one is the derived class? (Points : 5)        class GeometricObject is the derived class from Cylinder.
       They have nothing in common and therefore have no relationships.
       class Cylinder is the base class.
       class Cylinder is derived from GeometricObject. Question 3.3. (TCO3) Which of the following might be potential class(es) in an application? (Points : 5)        shape
       colorShape
       drawShape
       All of the above
       None of the above Question 4.4. (TCO3) What does SOW stand for in the object-oriented design process? (Points : 5)        Sequence of work
       Structure of work
       Statement of work
       None of the above Question 5.5. (TCO 4) In object-oriented programming, inheritance is transitive; that means a child class _____. (Points : 5)        inherits only from its parent class
       inherits only selected methods and fields
       inherits all the methods and fields of all its ancestors
       does not inherit any methods or fields Question 6.6. (TCO 6) _____ is the ability to use the same expression to denote different implementation depending on the type of object calling the expression. (Points : 5)        Inheritance
       Encapsulation
       Polymorphism
       Composition Question 7.7. (TCO 2) Which of the following is a proper implementation for a getter? (Points : 5)        int getDayOfBirth() { return day;}
       void getDayOfBirth() {return day;}
       int getDayOfBirth (int day) {this->day = day;}
       void getDayOfBirth () {return day;} Question 8.8. (TCO 4) Assuming the definition:

class Circle : public Point

Which of the following is false? (Points : 5)        The colon( : ) in the header of the class definition indicates inheritance.
       The keyword public indicates the type of inheritance.
       All the public and protected members of class Circle are inherited as public
and protected members, respectively, into class Point.
       Point is the base class and Circle is the derived class. Question 9.9. (TCO 1) Examine the class definition. How many members does it contain?

class Date
{
public:
void setDate(int, int, int);
void printDate() const;
int getDay(); int getDay(); int getDay();
private:
int day;
int month;
int year;
};
  (Points : 5)        8
       3
       6
       None of the above Question 10.10. (TCO 8) Data/information hiding and encapsulation improves construction and maintenance because: (Points : 5)        Programs become more self-documenting
       Procedural programming practices are supported
       Adding additional details is isolated to a single class
       All of the above
       None of the above Question 11.11. (TCO 8) What are some of the characteristics of "self-documenting" code? (Points : 5)        Detailed comments, addressing all aspects of the code
       Deep levels of nesting to ensure all situations are addressed
       Straightforward algorithms
       All of the above
       None of the above Question 12.12. (TCO 9) Which of the following allow a programmer to reduce the complexity of an object-oriented program? (Points : 5)        Create each class in a separate file
       Using namespaces as a container for logically related items
       Using namespace to create global types
       All of the above
       None of the above Question 1.1. (TCO 4) Which of the following is true about inheritance? (Points : 5)        Child classes are more generalized than their associated parent classes
       Parent classes are more specialized than their associated child classes
       Parent classes contain more functionality than child classes
       Inheritance demonstrates the generalization/specialization relationship
