Several things. One mistake is covered by Question 7.1
(see also Questions 7.2 and 7.3) in the comp.lang.c Frequently
Asked Questions list
http://www.eskimo.com/~scs/C-faq/top.html
Another of your mistakes doesn't seem to be covered in
the FAQ. Point to ponder: Where is the "scan pattern" or
"scan format" in your fscanf() call?
