//CLASS NOTE: as we build the floor G before floor 1 in a building,we are using the base class as floor G and  the derived class as floor 1
//thats why the groundfloor() is showing the constructed msg first and while destructing the upper floors are destroyed first
//we also work with the parameterized constrcutors 
//in base class,there is only the parameters of the base class
//in derived class,we put in all parameters from base and derived classes
