Question

Which of the following are true about Object-Oriented Programming (OOP).

Choose ALL that apply.
A. OOP allows us to define new classes
B. Use of inheritance allows us to reuse code without having to rewrite it
C. A parent class can have at most one child class in Python
D. All methods in the parent class must be overridden by the child class

Answer 1

Object-Oriented Programming allows defining new classes and using inheritance for code reuse. However, a parent class can have multiple child classes, and it is not required to override all methods of the parent class.

Step-by-step explanation:

Object-Oriented Programming (OOP) is a programming paradigm used in software development. When analyzing the given statements about OOP, it can be noted that the following statements are true:

• OOP allows us to define new classes, enabling programmers to create objects that have attributes and behaviors.
• Use of inheritance allows us to reuse code without having to rewrite it, by allowing a new class, called a child class, to inherit properties and methods from an existing class, known as the parent class.

However, the given statements that are false include:

• A parent class can have multiple child classes in Python, not just one.
• It is not necessary for all methods in the parent class to be overridden by the child class; a child class can inherit methods without modification.
