Would an introductory book on C (the Waite Group's C Primer Plus) from 1990 be worth reading, or have the basics of the language changed too much? The book's on generic (ANSI) C so there won't be worries about specific compilers or operating systems.

Thanks in advance!

EDIT: I've already taken a quarter-long class in C++ and am signed up to take the second one next quarter. I just want to do C for the fun of it. :-)
