You can have a case with several parameters:

Break effect is available by default. To cancel, add fallthrough:

Var I = 0switch I {case 0: fallthroughcase 1: fmt.Println ("1") case 2:fmt.Println ("2") default: fmt.Println ("def")}

Case can also be an expression:

Var I = 0switch {case I > 0 & & I

< 10: fmt.Println("i >

0 and i

< 10")case i >

10 & & I

< 20:fmt.Println("i >

10 and I < 20 ") default: fmt.Println (" def ")}
