The switch is used for programming a list of alternates.
No exit/egress is involved. The next statement after
the switch is always executed -- unless you've populated
it with gotos and exits ;)
Multiple exits are jsut that: multiple points of egress from
a function/subroutine. The problem with the latter is that
often there are some required exit conditions to be met
(i.e. setting up return values, destroy your mess, etc) that
make maintenance a nightmare if there many exit points. It
is very easy (too easy) to introduce subtle bugs in subroutines
that have multiple exit points.
