You can't do that, sorry.   Here's a gross oversimplification of why:
The  variable's "name" is usually something symbolic that makes it easier
for you to write your program.   Once the program has been compiled, that
name is gone -- it's working with addresses in memory instead.

So, you can't use data in a file to give you a variable name -- At least
not directly.

I'm not quite sure what you're trying to do.  Are you just looking for
examples of how to use pointers?   Or are you actually looking for
something more specific?

Perhaps if I had an idea of what you need to accomplish and why, I might
be able to show you a technique that would help...   can you send more
information?

Thanks!
