What have you tried so far? Why does it have to be unbuffered, other than
that is what the homework assignment says to do?
Start by accepting the file names (from stdin, or as command line
arguments).
Open the two files, one in read mode, the other in write mode. Be sure to
check for success.
If the input file is reasonably short, just read each line into an array of
strings, then write the strings to the output file in reverse order.
Then close the files.
If the file is very long, you might need to try something else (it might not
fit entirely in memory).
