Terminal program file sizes

I'm learning obj-c with cocoa from a book, and at the end of each chapter it has you create simple programs for practice. In that past hour or so, I've created several simple command-line programs, one short file each, and yet my hard drive space keeps dropping drastically (drastic compared to the amount of space these files should take up). Any ideas?

Thanks!

What is drastic? Open up the terminal, and go to one of the directories where you have your programs and issue the command "du -sch *" and it will give you an idea of how much space each directory and file is taking..
