your prof wants a loop I think, for the command line part.
There is a problem with arguments you need to know
you can reference $1 .. $9 the way I show. More than that and it becomes ${10} ${11} and so on. I would suggest using the shift command to move each argument into the $1 variable.
you need a loop for the arguments as well
