Why do you think modeling real-world concepts as objects can be beneficial in programming?

Multiple Choice

Which of the following best describes the concept of an object in Object-Oriented Programming (OOP)?

• A self-contained entity with its own state and behavior

• A function that performs a specific task

• A variable that stores data temporarily

• A set of instructions executed in sequence

Multiple Choice

Which of the following best describes the relationship between a class and an object, based on the book analogy provided?

• A class is a specific book, and an object is the blueprint for all books.

• A class is the blueprint for all books, and an object is a specific book created from that blueprint.

• A class and an object are the same thing in programming.

• A class is the author, and an object is the book.

Multiple Choice

What is the primary purpose of a constructor in a class?

• To destroy objects when they are no longer needed

• To initialize the attributes of a new object and allocate memory for it

• To define the behaviors of an object

• To create methods for an object

Fill in the Blanks

A method is a

or procedure that belongs to an object.

Multiple Select

Which of the following are considered attributes (or properties) of a book object, according to the analogy?

• Title

• Number of pages

• openBook()

• Current page number

Open Ended

Explain how methods and attributes differ in the context of an object, using the book analogy.

Open Ended

How does abstraction help in object-oriented programming, and what is a real-world analogy for it?

Open Ended

How does the analogy of a car's engine and its interface help explain the concept of encapsulation?

Multiple Choice

Which of the following best describes encapsulation in object-oriented programming?

• Allowing direct access to all internal data of an object

• Hiding the internal workings and data of an object from external components

• Sharing methods between unrelated objects

• Automatically inheriting attributes from another class

Multiple Choice

Which of the following statements about inheritance is correct?

• A derived class can only inherit methods, not attributes.

• Inheritance allows a new class to be created based on an existing class, inheriting all attributes and methods.

• Inheritance prevents a class from overriding methods.

• A class can only inherit from one parent class.

Fill in the Blanks

Polymorphism enables a single method name to be

across an object hierarchy.

Multiple Select

Select all the correct statements about overriding in object-oriented programming.

• Overriding allows a derived class to provide its own implementation for a method defined in its parent class.

• Overriding is not related to polymorphism.

• Overriding replaces the parent's default behavior for a method when invoked on an object of the derived class.

• Overriding prevents the use of virtual methods.

How does the analogy of a physical book help you understand the concept of an object in OOP?

Multiple Choice

What is an object in the context of Object-Oriented Programming (OOP)?

• A function that performs calculations

• A fundamental building block representing a real-world thing or concept

• A type of variable that stores only numbers

• A process for organizing code into steps

Multiple Choice

What is the main difference between association and stronger forms of relationships like aggregation and composition in object-oriented design?

• Association is a general relationship, while aggregation and composition are specific, stronger forms of association.

• Association means one class is part of another, while aggregation does not.

• Aggregation and composition do not involve any interaction between classes, while association does.

• Association is only used for inheritance, while aggregation and composition are not.
