C#OOPS

  OOPS (Object-Oriented Programming) topics in C#

1. Class: A class is a blueprint for creating objects. It defines the properties (data) and methods (functions) that objects of the class will have.

2. 
   

3. Object: An object is an instance of a class. It contains real values instead of variables, and it has access to class methods.

4. 
   

5. Inheritance: Inheritance is a mechanism in which a new class (derived class) is created from an existing class (base class). The derived class inherits the properties and methods of the base class.

*Extension of Method

1. 
   

2. Polymorphism: Polymorphism allows objects of different classes to be treated as objects of a common superclass. It enables methods to do different things based on the object that they are acting upon.

*Single Entity which can be used in many Forms

1. 
   

2. Encapsulation: Encapsulation is the bundling of data and methods that operate on the data into a single unit (class). It hides the internal state of an object from the outside world and only exposes the necessary functionalities.

*Wrapping Data or Code in a Container

1. 
   

2. Abstraction: Abstraction is the process of hiding the complex implementation details and showing only the essential features of an object. It allows for managing complexity by focusing on what an object does rather than how it does it.

*Hiding Unnecessary Data

1. 
   

2. Constructor: A constructor is a special type of method that is automatically called when an object of a class is created. It initializes the object's state.

3. 
   

4. Destructor: A destructor is a special method that is automatically called when an object is destroyed or goes out of scope. It is used to release resources held by the object.

5. Method Overloading: Method overloading allows multiple methods in a class to have the same name but with different parameters. The method to be called is determined by the number and types of arguments passed.

6. 
   

7. Method Overriding: Method overriding is a feature that allows a subclass to provide a specific implementation of a method that is already defined in its superclass. It is used to achieve runtime polymorphism.
