virtualized function - is that something along the lines of a constructor. that
is, a variable initializing a class

(latter on :) ), it said we
cant use a less restrictive (private here) specifier in derived class then
the base class. its in oop principle, so this kind of examples are on the
responsibility of programmer cause c++ is weakly checked language ( we all
know that it is on the cost of more disciplined programmer :) ).
so it is not at all opp so its not a violation
(i got this answer latter so i am sharing with u all i was not intended to
take any kind of test or give any challenges)
