	1. Create a file called mongoose.txt (or pick a different name
	   and change the fileName[] initialization below) containing
	   a few lines of text.  You can, of course, do this with an
	   editor.  A handy technique for making small test files without
	   leaving your Unix window is this:
	   
	     prompt> cat > mongoose.txt
		 These are
		 some words in
		 my test file.
		 Yipee.
		 <CTRL-D>
		 prompt>
	
	   You can check to see whether "cat" (which stands for "concatenate")
	   made your new file properly by typing "cat mongoose.txt" or
	   "more mongoose.txt".
	   
	   To add some stuff to the end of an existing file, you can do
	   this:
	   
	     prompt> cat >> mongoose.txt
		 New stuff for the end.
		 <CTRL-D>
		 prompt>
	
	   Try it out.  If you're curious about "cat", "man cat" is always
	   available to you.
	
	2. Compile and run this program.  Why did I put at-signs in the
	   output?
	
	3. When you use fscanf(), does "%s" match the whole rest of the
	   current line of text, or does it match only the next word?
	   Does "%s" discard initial white space, or does it include
	   spaces and tabs in the string it gives you?  What if you
	   try to match "%s" and the current line is a blank line--does
	   fscanf() read past the newline character in search of a string?
