Two Questions.

[Steve L Vissage II]

I'm just learning C.  The introductory book I used was Herbert Schildt's 
"C: The Complete Reference", which covers the ANSI standard, and Unix C.
  
I think the only thing the book doesn't explain well is far pointers.  Would
one of you be kind enough to enlighten me through e-mail?  I'd like a brief
technical definition, and a more indepth explanation of how they're different
from regular pointers, specifically how usage differs.
 
Second, I've been thinking about a project that would require something like
self-modifying code.  I want to write a C program which can take input from
the keyboard, a word, say, and declare a structure by that name.  In other
words, I have the name of a structure in a variable, is it possible to declare
that structure using the variable?
 
Thanks for your help, and I'll be getting back to you.
