no explanation about l1: could be find on google or any documentations. 🙂 Please if someone could explain why defualt: generated those two errors (warnings) I would be grateful. Thanks in advance XO

It's a typo! It should be default:

the syntax Identifier: is labaled statement, used with goto because you dont have any goto to defualt (which is typo) and the statement placed after break; so the compiler warn you unused label and unreachable code

Thank you. I wanted to know why the compiler recognizes it as a label, and what even is a label in that context Thanks Thank you very much.
