For i :=1 ; i<100 ; i++ { switch

Question

For i :=1 ; i<100 ; i++ { switch

i {
case i%3 == 0 && i%5==0:fmt.Println("FizzBuzz")
case i%3 == 0:fmt.Println("Fizz")
case i%5 == 0:fmt.Println("Buzz")
default: fmt.Println(i)
}

errors :
/main.go:39:3: cannot use i % 3 == 0 && i % 5 == 0 (type bool) as type int
./main.go:40:3: cannot use i % 3 == 0 (type untyped bool) as type int

wow . thanks Roman . the only difference is : we should not pass the variable to the switch statement . so if we pass a variable name to the switch statement , then we should just compare the value of that variable ( we can't evaluate some condition ) but , if we don't pass any variable to switch , then we can evaluate as much as condition .

You can't assign condition to case statement, if you want to give condition then use if - else
