Warning digit1 may be used uninitialized in this function

@SteveMann

This makes sense, but why don't I get the same warning for digit3?

You don't read answers? I should note that, and not participate in threads of yours.

@Whandall

The difference is the default case that makes sure, that digit3 always gets a value,
that is not the case for the first switch, that sets digit1.

So the compiler sees a flow of execution, that leaves digit1 uninitialized when used.
