Question 5

Here is some pseudocode that uses object-oriented programming:

Match each highlighted part of of the pseudocode to the term that describes it.

Question 5 options:

method call

object

method

Class name

member variable, field, or property

Parent class

AlcoholicIngredient

Ingredient

_volume

calc_total_alcohol

ingredient

ingredient.input

Question 6

Which of the following statements is most correct?

Question 6 options:

An object is an instance of a class.

A class is like a house; an object is like the blueprint for that house.

"Class" and "object" are different terms for the same thing.

A class is an instance of an object.

Question 7

Match each term below with the best description.

Question 7 options:

Everything you know about a class and everything you know how to do with that class are contained within the class definition.

Each subclass provides the same interface so that outside code doesn't have to know what kind of subclass is being referenced. For example, a SquareShape provides a draw method that draws squares, while a CircleShape provides a draw method that draws circles. Outside code just tells the object to draw, without needing to know whether a circle or a square will be drawn.

Properties and methods that are common to all subclasses are contained within a parent class. Child classes can access these properties and methods as if they were defined as part of the child class.

Certain properties and methods of a class are marked "Private" and can only be accessed through a "Public" interface. This gives the programmer a certain amount of freedom to change the implementation, without breaking anyone else's code.

Encapsulation

Data Hiding

Inheritance

Polymorphism
