CS 243 Homework #4

In your home directory,
 create a subdirectory named: homework4

Part 1:
In your homework4 directory,
 create part1.c, compile, and run part1
  which should do the following:
   read two arguments from the command line:
      cmd line arg1 should be a string of letters
      cmd line arg2 should be a simple file basename
  Your program should
   write the arg1 letters
    followed by newline
     to the arg2 file
      in the current directory.
       Create the file if it does not already exist.
        Append to the file if it already exists.
Hint: see pages 135-137.

Note: do not use getopt.
   Assume the arguments are passed in the correct order.
