c# programming
There are four fundamental OOP (Object Oriented Programming) concept they are listed as follows:
- Inheritance- Ever heard of this dialogue from relatives “you look exactly like your father/mother” the reason behind this is called ‘inheritance’. From the Programming aspect, It generally means “inheriting or transfer of characteristics from parent to child class without any modification”. The new class is called the derived/child class and the one from which it is derived is called a parent/base class.
- Polymorphism- You all must have used GPS for navigating the route, Isn’t it amazing how many different routes you come across for the same destination depending on the traffic, from a programming point of view this is called ‘polymorphism’. It is one such OOP methodology where one task can be performed in several different ways. To put it in simple words, it is a property of an object which allows it to take multiple forms.
- Encapsulation- In a raw form, encapsulation basically means binding up of data in a single class.A class shouldn’t be directly accessed but be prefixed in an underscore.
- Abstraction- Suppose you booked a movie ticket from bookmyshow using net banking or any other process. You don’t know the procedure of how the pin is generated or how the verification is done. This is called ‘abstraction’ from the programming aspect, it basically means you only show the implementation details of a particular process and hide the details from the user. It is used to simplify complex problems by modeling classes appropriate to the problem.An abstract class cannot be instantiated which simply means you cannot create objects for this type of class. It can only be used for inheriting the functionalities.
