CIE As A level Chpt_20: Object-Oriented Programming

What is the primary goal of Object-Oriented Programming (OOP)?

• To write programs that execute faster

• To make programs structured and reusable by organizing code around objects

• To increase the complexity of code

• To reduce the use of functions

Which of the following best describes an object in OOP?

• A block of code inside a loop

• A function within a program

• A real-world entity represented in programming

• A set of unrelated variables

What is encapsulation in OOP?

• Dividing a program into multiple loops

• Hiding the internal details of an object and exposing only the required functionalities

• Combining multiple classes into one

• Overloading methods

Which of the following is NOT an OOP principle?

• Encapsulation

• Abstraction

• Inheritance

• Compilation

What does abstraction in OOP achieve?

• Revealing all implementation details

• Providing only essential features and hiding complex details

• Extending a class

• Combining different programs into one

What does inheritance in OOP allow?

• Copying an object

• Defining a new class based on an existing class

• Deleting attributes from a class

• Creating private methods

Which of the following is an advantage of OOP?

• It makes code easier to debug by avoiding modularity

• It allows for reusability and better organization of code

• It forces the programmer to use only one class

• It eliminates the need for abstraction

What is a class in OOP?

• A specific object in memory

• A blueprint for creating objects

• A function that runs automatically

• A variable storing data

Which principle of OOP involves using common methods in different classes with different implementations?

• Inheritance

• Polymorphism

• Encapsulation

• Abstraction

Which of these is a drawback of Object-Oriented Programming?

• It improves program complexity.

• It has a steep learning curve compared to procedural programming.

• It eliminates debugging issues.

• It reduces modularity.
