The program compile successfuly and I could link all the obj files
without any errors or warnings. When I execute the
application(ll.exe), I can input all the numbers but the link list is
not printed. I think the problem lies in the fact that the link list
has been created but the copy of updated pointer to the root node is
not available as it got destroyed once the create routine terminated.

I didn't get destroyed, it got lost. See the FAQs:
