Can someone help me in below code, I have used both if and switch to compare string in golang but both of them are not working

Question

package main
import "fmt"
//import "strings"
func main() {
results := []string{"w", "l", "w", "d", "w", "l", "l", "l", "d", "d", "w", "l", "w", "d"}

var x string
fmt.Scanln(x)
a := "w"
b := "d"

/* if strings.Compare(x,a) == 0{
fmt.Println(22)
}else if x == b {
fmt.Println(20)
}else if x == "l"{
fmt.Println(19)

} */

switch x{
case "w":
fmt.Println(22)
case "d":
fmt.Println(20)
default :
fmt.Println(19)

}
results = append(results ,x)
}

Answer 1

You missed to return the address of your input variable.
fmt.Scanln(&x)

It's not necessary to declare variables if you don't want to assign them.
//a := "w"
//b := :d"

or if you want to use them
switch x{
case a:
fmt.Println(22)
case b:
fmt.Println(20)
default :
fmt.Println(19)

}
