//created an array of base class and to each element we assigned a different type of base class object
// now create an array to loop through each base class object
// since we have a base class reference variable referenceing to child classses, though we have the method in child overriding parent class
//the base class method is called
// the new keyword is used to hide the base class but our intension is to override the definition provided by base class, use override
// for this mark the parent method virtual
// this indicated the child class that it can override the parent class if it wishes to do so
//though the ref variable is of type parent, the runtime checks the type of object, then it invokes the overriden method in the child class
// this is called polymorphism
// Polymorphism enables us to invoke the derived class methods using base class reference variables at run time
// if the child class do not have any implementation overriding the parent class, then the parent class method is executed
