A: While derived class overrides the base class method through redefining the same function, then if client wished to access redefined the method from derived class via a pointer from base class object, then you have to described this function in base class as virtual function.

class parent                       

{

void Show()

{

cout << "i''m parent" << endl;

}

};

class child: public parent

{

void Show()

{

cout << "i''m child" << endl;

}

};

parent * parent_object_ptr = new child; parent_object_ptr->show() // calls parent->show() now we goto virtual world...

class parent

{

virtual void Show()

{

cout << "i''m parent" << endl;

}

};

class child: public parent

{

void Show()

{

cout << "i''m child" << endl;

}

};

parent * parent_object_ptr = new child;

parent_object_ptr->show() // calls child->show()
