What is difference between abstraction and inheritance

Abstraction

Abstraction hides the internal implementation details and shows only the necessary features of an object.

How it's done in C#:

• Using abstract classes and interfaces.

Sample Code :

abstract class Animal

{

    public abstract void MakeSound(); // Abstract method

}

class Dog : Animal

{

    public override void MakeSound()

    {

        Console.WriteLine("Bark");

    }

}

• Animal is an abstract class that defines a contract.
• Dog provides the actual implementation.

--------------------

Inheritance:

Inheritance allows a class to inherit members (fields, methods, properties) from another class.

How it's done in C#:

• Using the : symbol to derive a class from a base class.

Sample Code:

class Animal

{

    public void Eat()

    {

        Console.WriteLine("This animal eats food.");

    }

}

class Dog : Animal

{

    public void Bark()

    {

        Console.WriteLine("Dog barks.");

    }

}

• Dog inherits the Eat() method from Animal.

Abstraction: Hides complexity by showing only essential features and hiding implementation details.

Inheritance: Enables code reuse by allowing a class to inherit members (fields, methods) from another class.
