    What is the purpose of Inheritance in Object-Oriented

    Programming?                            
    A To allow one object to create another object Correct Answer Incorrect Answer
    B To allow one class to inherit properties and methods from another class Correct Answer Incorrect Answer
    C To enable the hiding of internal details of an object Correct Answer Incorrect Answer
    D To allow the association between two independent objects Correct Answer Incorrect Answer
    E To enable communication between objects of different types Correct Answer Incorrect Answer

    Solution

    Inheritance is a key feature of Object-Oriented Programming (OOP) that allows a class (called the derived or child class) to inherit properties and methods from another class (called the base or parent class). This helps in reusing code and establishing hierarchical relationships between classes. The derived class can access and modify the behaviors of the base class, and it can also add its own additional methods and properties.

    • Why It Is Important: Inheritance promotes code reuse , reduces redundancy, and enhances maintainability. It also enables the creation of a hierarchical relationship between classes, where a base class defines general behaviors, and derived classes specialize or extend those behaviors. This leads to a more organized and structured codebase.
    • Real-World Example: Consider a class Vehicle with methods like start() and stop() . A subclass Car can inherit these methods from Vehicle and add its own methods, such as playMusic() , without having to re-implement the start() and stop() methods.
    Why Other Options Are Incorrect:
    •   To allow one object to create another object: This describes object creation or composition , not inheritance.
    • To enable the hiding of internal details of an object: This refers to encapsulation , not inheritance.
    • To allow the association between two independent objects: This refers to association or aggregation , not inheritance.
    • To enable communication between objects of different types: This is an example of polymorphism or message passing , not inheritance.
