Thank you. I got it.It just separately compiler problem.

In other words, you just want your assignment finished and you're not really interested in good programming practice?! I've already told you how to do it. Put your template definitions in the header; don't make a separate source file. If you insist on a separately compiled source file for templates, then you need to employ explicit template instantiation.
