Homework, eh? Well, here's a few *hints*, then.
Processes (or commands) are executed in the context of a shell.
Therefore, it's the shell that has the exit status of the process. You
need to find out just how to query the shell for that.
Look in the 'bash' manpage (or docs) and search for the various
automatically defined environment variables. Some of them include $#
which says how many command line args are used in a script and $@ which
is the args list. The variable to return the exit status is something
like those.
