Questions using normalized routine code is the basic respect to answer the question...

 # include & lt; Iostream>//should be here no. J h, will. H to remove 

Class c 
{
(c) 
{
Cout<" The base class constructor \ n "& lt; }
~ (c) 
{
Cout<" Base class destructor \ n "& lt; }
}; 

Class d: public c 
{
(d) 
{
Cout<" The derived class constructor \ n "& lt; }
~ d () 
{
Cout<" The derived class destructor \ n "& lt; }

};

using namespace STD.//sure use namespace
