G12 Advanced Theory

Why is OOP considered more structured and reusable compared to procedural programming?

• Because it forces all functions to be global

• Because it organizes data and behavior into objects that interact in a modular way

• Because it removes the need for defining variables

• Because it prevents code from being executed more than once

How does the __init__ method contribute to encapsulation?

• It prevents attributes from being modified after instantiation

• It initializes attributes and ensures they are assigned values when an object is created

• It encrypts attributes so they cannot be accessed

• It restricts the creation of objects to specific classes

Why is self required in class methods?

• It allows each method to modify class-level attributes

• It ensures that methods can only be called from within the class

• It allows access to instance attributes and methods within the object itself

• It automatically generates unique attribute names for every instance

What advantage does inheritance provide in large-scale software development?

• It prevents classes from being modified after creation

• It reduces code duplication by allowing shared functionality across multiple classes

• It makes all attributes private by default

• It forces all classes to follow the same method structure

How does the super() function help maintain modular and extensible code?

• It enforces strict typing rules for all attributes

• It ensures that attributes from the parent class are inherited without redefining them

• It prevents attributes from being accessed outside the class

• It forces method names to be unique in child classes

What is a key principle of polymorphism that makes code more flexible?

• It allows the same method name to have different implementations in different classes

• It requires all methods in a class to have unique names

• It prevents child classes from modifying inherited methods

• It forces all attributes to be public

How does method overriding support polymorphism?

• It allows a child class to define a method with the same name but different behavior from the parent class

• It forces all child classes to use methods exactly as defined in the parent class

• It prevents methods from being inherited by child classes

• It ensures all methods return the same data type

What problem does encapsulation solve in software design?

• It prevents functions from being executed outside a class

• It allows controlled access to an object's attributes, preventing unintended modifications

• It forces all attributes to be public, ensuring flexibility

• It makes objects immutable after instantiation

Why would a programmer use a getter method instead of accessing an attribute directly?

• To add validation or processing before returning the attribute's value

• To prevent an attribute from being used by any method

• To force all attributes to be accessed through class methods

• To make attributes automatically update their values when accessed

How does an abstract class contribute to polymorphism?

• It prevents method names from being repeated across different classes

• It defines a common interface that multiple child classes can implement in their own way

• It forces all child classes to use the same implementation for all methods

• It prevents child classes from overriding methods
