Inheritance is the ability to define a new class or object that inherits the behavior and its functionality of an existing class. The new class or object is called a child or subclass or derived class while the original class is called parent or base class.

In other words when a class acquire the property of another class is known as inheritance.We can say that, inheritance is the second pillar of OOPs because with the help of single class we can’t make our project.  Through inheritance we can achieve code reusability and encapsulation. How?

Ans – code reusability….

Here we have made a function with name Info in class BASEand that function performs Xtask.  We have one more class too named is Derive.  Derive class wants to use base class function.

Now, there are two methods- one is we can create Info function again in class Derive second is we can simple inherited class BASE and call Info function. This method is called code reusability.

using System;
namespace inheritance
{
    class BASE
    {
       public void Info()
        {
            Console.Write("Enter Your Name...");
            string name=Console.ReadLine();
            Console.Write("Enter Your Address...");
            string add = Console.ReadLine();
            Console.WriteLine(name);
            Console.WriteLine(add);
           Console.ReadLine();
        }
    }
 
    class Derive:BASE
    {
        static void Main(string[] args)
        {
            Derive d = new Derive();
            d.Info();
        }
    }
}

Ans – Encapsulation…
