Method overriding in C# is a feature of object-oriented programming that allows a subclass to provide its own implementation of a method that is already defined in its superclass. This means that when the subclass calls the method, its own implementation will be executed instead of the superclass's implementation. To override a method in C#, you need to use the `override` keyword in the subclass method definition. The overridden method in the superclass must be marked as `virtual` or `abstract`. Here is an example of method overriding in C#: ``` class Animal { public virtual void MakeSound() { Console.WriteLine("The animal makes a sound"); } } class Cat : Animal { public override void MakeSound() { Console.WriteLine("Meow"); } } ``` In this example, we define a class called `Animal` with a virtual method called `MakeSound()`. The `virtual` keyword allows subclasses to override this method. We then define a subclass called `Cat` that overrides the `MakeSound()` method with its own implementation. When we call the `MakeSound()` method on a `Cat` object, the subclass's implementation will be executed: ``` Animal myAnimal = new Animal(); Cat myCat = new Cat(); myAnimal.MakeSound(); // outputs "The animal makes a sound" myCat.MakeSound(); // outputs "Meow" ``` In this example, calling `MakeSound()` on the `Animal` object will execute the `Animal` class's implementation, while calling `MakeSound()` on the `Cat` object will execute the `Cat` class's implementation, demonstrating method overriding.| Method overriding in c#| method overriding

 What is method overriding in c#?


Method overriding in C# is a feature of object-oriented programming that allows a subclass to provide its own implementation of a method that is already defined in its superclass. This means that when the subclass calls the method, its own implementation will be executed instead of the superclass's implementation.


To override a method in C#, you need to use the `override` keyword in the subclass method definition. The overridden method in the superclass must be marked as `virtual` or `abstract`.


Here is an example of method overriding in C#:



class Animal

{

    public virtual void MakeSound()

    {

        Console.WriteLine("The animal makes a sound");

    }

}


class Cat : Animal

{

    public override void MakeSound()

    {

        Console.WriteLine("Meow");

    }

}



In this example, we define a class called `Animal` with a virtual method called `MakeSound()`. The `virtual` keyword allows subclasses to override this method. We then define a subclass called `Cat` that overrides the `MakeSound()` method with its own implementation.


When we call the `MakeSound()` method on a `Cat` object, the subclass's implementation will be executed:



Animal myAnimal = new Animal();

Cat myCat = new Cat();


myAnimal.MakeSound(); // outputs "The animal makes a sound"

myCat.MakeSound(); // outputs "Meow"



In this example, calling `MakeSound()` on the `Animal` object will execute the `Animal` class's implementation, while calling `MakeSound()` on the `Cat` object will execute the `Cat` class's implementation, demonstrating method overriding.
