I'm haveing real trouble I'm getting this error expected unqualified~id before 'switch' for this code

which I heavley modified from an exampleI found on the web. the compiler says the error is in in the line in red but I just cant see whats wrong please help
Robin2:
SWITCH just takes the name of a variable so it should be
No, "switch" takes any integer expression, but obviously with a comparison as that expression, the range of possible cases is severely limited.
I was going to post, in fact I did then deleted it, exactly what Robin said. But when I took the comparison out, it still gave the OP's quoted compile error. I realised that it's legit as code, although as you say AWOL, the cases then need to have passed the test first. Interesting.....
