Before electronically submitting your project code, use tar and gzip to create a compressed "tape" archive file of your project directory:
  1. First make sure that your code is sitting in its own subdirectory, e.g., in my case, my code is in my .../array directory: 
    	[andrewd@pupil] ~/teaching/cpsc102/src/examples/array > ls
	Makefile        array.h         dops*           templated/
	array.cpp       dopdf*          non-templated/  yarra.cpp
	[andrewd@pupil] ~/teaching/cpsc102/src/examples/array >
  2. Do a make clean to clean up all the *.o and executable files (to reduce space): 
    	[andrewd@pupil] ~/teaching/cpsc102/src/examples/array > make clean
	rm -f array.o  core yarra.o yarra
	rm -f *.ps *.pdf
  3. Change directories to one above the current project directory, e.g.: 
    	[andrewd@pupil] ~/teaching/cpsc102/src/examples/array > cd ..
	[andrewd@pupil] ~/teaching/cpsc102/src/examples >
  4. Create the tar file. The command syntax is: 
    	tar cvf <file.tar> <directory>
    where <file.tar> is the tar file being created, and <directory> is the directory which will get archived (stuffed) into the single tar file. You'll see a list of a <directory/file> additions being assembled into the tar file. You will then have the file <file.tar>. 
    	[andrewd@pupil] ~/teaching/cpsc102/src/examples > tar cvf array.tar array/
	array/array.cpp
	array/array.h
	array/Makefile
	array/yarra.cpp
	...
  5. Compress the tar file using gzip: 
    	[andrewd@pupil] ~/teaching/cpsc102/src/examples > gzip array.tar
    You'll now see the file <file.tar.gz>. This is the file you want to submit electronically.
