Switch statement / default:

I know that the "default:" is optional in a switch statement, and if not a part of the switch statement and no values match any case statements, there would be no action. If, however, a default is included and there is no action to take under the default, and a value that had no case statement for that value, and was therefore passed down to the default, could there be any action that may cause faults to the program being executed?

Thanks.

What do you mean by "cause faults to the program being executed"?

Could there be a possibility of the program crashing, for example?

No, except due to some other problem.

I didn't think so, but wanted another opinion of a real expert.

Thanks LL
