Creating my first Shell Script

I have an assignment in my programming class to write a shell script that will use command line parameters, display the # of parameters, display all parameters on the command line and display the parameters $0-$9. I understand some of the code (I will be using 'n' to represent the count through the 'for' loop), but I don't understand how to display $0-$9 inside the loop. The book I am using dosen't explain it very well (Unix Unbounded a Beginning Approach - Amir Afzel). My instructor isn't very helpful either. Can someone please give me some examples? Also, how do you echo a message to say $# = 5, etc.?

Read the rules, there's a link at the bottom of every page. Note rule 6.
