Object Oriented Programming Concepts

What is inheritance in object oriented programming?

• Inheritance is the mechanism by which a class loses its properties and behaviors to another class

• Inheritance is when a class cannot acquire the properties and behaviors of another class

• Inheritance is the mechanism by which one class acquires the properties and behaviors of another class.

• Inheritance is the process of creating a new class from an existing class

Explain the concept of polymorphism with an example.

• Polymorphism refers to the ability of a method to perform different actions based on the object that it is acting upon.

• Polymorphism is the ability of a class to inherit from multiple parent classes.

• An example of polymorphism is a shape class with different subclasses like circle, square, and triangle. Each subclass has its own implementation of the area method, but they can all be treated as shapes and called using the same interface.

• An example of polymorphism is a car class with different subclasses like sedan, SUV, and truck.

How does encapsulation help in object oriented programming?

• Encapsulation helps in restricting access to certain components of an object.

• Encapsulation has no impact on object oriented programming.

• Encapsulation helps in increasing the complexity of the code.

• Encapsulation allows unrestricted access to all components of an object.

What is abstraction and why is it important in OOP?

• Abstraction is the process of making code more complex and difficult to manage

• Abstraction is the concept of hiding the complex implementation details and showing only the necessary features of an object. It is important in OOP because it allows for the creation of simplified and manageable code, and helps in reducing complexity and increasing efficiency.

• Abstraction is only used in procedural programming, not in OOP

• Abstraction is not important in OOP as it adds unnecessary complexity

Differentiate between class and object in OOP.

• A class is an instance of an object, while an object is a blueprint for creating classes.

• A class is a variable in OOP, while an object is a function.

• A class is a method in OOP, while an object is a data type.

• A class is a blueprint for creating objects, while an object is an instance of a class.

What is method overriding and how is it implemented in OOP?

• Method overriding is implemented by creating a method in the subclass with different parameters than the method in the parent class.

• Method overriding is implemented by creating a method in the subclass with a different name than the method in the parent class.

• Method overriding is implemented by creating a method in the subclass with a different return type than the method in the parent class.

• Method overriding is implemented by creating a method in the subclass with the same name, return type, and parameters as the method in the parent class.

Give an example of inheritance in real life.

• Acquiring a new language through immersion

• Genetic traits passed down from parents to children

• Inheriting a family heirloom

• Learning a new skill from a teacher

Discuss the advantages of using polymorphism in OOP.

• Polymorphism leads to increased complexity and decreased efficiency

• Polymorphism allows for flexibility and reusability of code.

• Polymorphism allows for creating duplicate code

• Polymorphism makes code inflexible and not reusable

Explain the concept of data hiding in encapsulation.

• Data hiding is the concept of encapsulation that allows the implementation details of a class to be easily accessible.

• Data hiding is the concept of encapsulation that allows the implementation details of a class to be hidden from the outside world.

• Data hiding is the concept of encapsulation that allows the implementation details of a class to be shared with other classes.

• Data hiding is the concept of encapsulation that allows the implementation details of a class to be visible to the outside world.

Why do we use abstraction in OOP?

• To slow down the program

• To simplify complex systems and show only essential features

• To confuse other programmers

• To make the code more complicated
