Can
the last case of a switch statement skip including the
break?
Answer:
Even
though the last case of a switch statement does not require a
break statement at the end, you should add break statements
to all cases of the switch statement, including the last case. You should do so primarily
because
your program has a strong chance of being maintained by someone other than you
who might add cases but neglect to notice that the last case has no break statement.
This oversight would cause what would formerly be the last case statement to
“fall through” to the new statements added to the bottom of the switch
statement.
Putting a break after each case statement would prevent this possible mishap and
make your program more “bulletproof.” Besides, most of today’s optimizing
compilers will optimize out the last break, so there will be no
performance degradation if you add it.
