I have found this switch statement and can someone explain to me how it works?
How does case 2 work If case 1 with declaration of b is omitted?

Thanks for replying.
I thought that code before case 2 is ignored. But it is not true. It is twisty piece of code anyway.
Cheers!

You assume scope that doesn't exist. All local variables are in the scope of the switch's body block. Try adding scope to the first case label like so:

We know that variable who is declared inside of {} cannot cannot be reached outside
