d.fun() will call the derived class fun() method.

d.fun(int) will call the fun(int) method which is in the base class as it is not existing in base class.

d.fun() will call fun() of derived class and for d.fun(77) since no match is found in derived class complier will search for matching typecast in base class.

Thus it will find fun(int i) and will execute it.

Its produces a warning during override. It would be avoid by using override keyword.

New keyword should be in the method func() of derived class to remove the warning.

Whenever we are calling a Method the compiler First searches for the method in Derived class, if it doesnot finds it there. Then it searches it in base class.

Since fun() is available in Derived class. So it executes it. Rather than executing the base class fun().
