Homework notwithstanding consider the following:
If it sufficiently small to store in memory
open the file
read the whole file into dynamic storage
close the file
else
copy the file (or rename it) somewhere else
open the file for writing positioned at the beginning of the file
write the single new character
Depending on the conditional above
either write the contents straight from dynamic storage into the
file just like the last character
or
read from the copy/renamed version of the original file and
write into the new one
close the file
exit
If that doesn't get you anywhere, drop the class or hire a tutor.
