another try

set -- -q -q200 -v -v400

  for arg ; do
 [[ $arg != -* ]] &&
continue # no arg
pre=${arg%%[0-9]}
 if [[ $arg == *[0-9] ]] ; then
num=${arg##[!0-9]?}
printf 'arg %s num %s\n' "$pre" "$num"
 else
printf 'arg %s nonum\n' "$pre"
 fi
  done

~ $ bash c.2
arg -q nonum
arg -q20 num 200
arg -v nonum
arg -v40 num 400

How can I handle the aforementioned functionality in a clear and compact
