Command-line arguments.

My program isn't accepting the filename I give on the command line. For
example, when I type "./a.out darwin.txt" it doesn't do anything.

  Write a small test program that does nothing but prints the command-line
  arguments to std-out one argument per line:

    $ ./a.out darwin.txt
    darwin.txt

    $ ./a.out hello world
    hello
    world

    $

  If you can get that to work, modify your test program to treat each
  command-line argument as a file name: have your program open the file and
  write the file's contents to std-out. If you can do that, you should be good
  to go. If you can't, let me know and we'll work through it.

  In general, it's a good idea to get in the habit of writing small programs to
  test some aspect of a language or a system that you're having trouble
  understanding.
