1. Why to name the file as such a long name? It doesn't conform to the
brief style of C!

2. update must haven't occured in the file! Otherwise, I can't imagine
what happened!

Open the file in an edittor and look for all occurences of the string 'update'
and verify you are indeed defining it somewhere. If you are expecting it to be
defined in a library, you need to include the library when you link.

# # gcc part09_iti_r01_ch09_ver01_file_processing_file_del etions_TV_Rental_bills.c
# Undefined first referenced
# symbol in file
# update /var/tmp/cckNzwjb.o
# ld: fatal: Symbol referencing errors. No output written to a.out
# collect2: ld returned 1 exit status
