   and it correctly called the Node destructor for each element of the   
   list, without having to cross the list and delete Nodes   
   individually. As Ian Collins suggested me to do.   
   I thought I made some error in building the list.   
      
   I didn't explicitly called delete on head because I thought head going   
   out of scope, the delete operator would have been called   
   automatically.  As you rightly say, I should have encapsulated head   
   into a class and then its destructor would have been called and the   
   list destroyed.  I'll try out this solution.   
      
   But pardon me the question: what is a smart pointer?   
      
   Oo Tiib suggested me to use std::unique_ptr   
   But I don't know   
   what is it and how to do it.   
      
   You are forgetting I'm a very beginner of C++   
      
   Thank you for your replies
