4. Create a base class Base with an abstract print() method that is overridden in a derived class Derived. The overridden version of the method prints the value of an int variable defined in the derived class. At the point of definition of this variable, give it a nonzero value, say, 11. In the base class constructor, call this method. In main(), create an object of the derived type, and then call its print() method. Explain the results. (1 point)
