6.) Overloading in case of inheritance

public class MyBaseClass
    {
        public void foo(int i)
        {
            Console.WriteLine("The is one parameter function which takes 
int as parameter and value of i is {0}.", i);
        }
    }

    public class MyChildClass : MyBaseClass
    {
        public void foo(string s)
        {
            Console.WriteLine("The is one parameter function which takes 
string as parameter and value of s is {0}.", s);
        }
    }

Here overloading is done on a function present in base class this is different from method hiding in way that hiding hides the implementation of base class while in this case both the implementations will co-exist in child class.

Let’s now create object of this class and call both the versions:-

   MyBaseClass obj = new MyBaseClass();
            obj.foo(10);
            MyChildClass obj2 = new MyChildClass();
            obj2.foo("Test");

Here is the output:-

The is one parameter function which takes int as parameter and value of i is 10.
The is one parameter function which takes string as parameter and value of s is Test.
