Go Lang -> If Statements -> Code Challenge (Blackjack)

You're so close! You got the syntax right, but Go is a little more picky about some of its flow-control token and brace placement.

Go's "if" statement is dependent on keeping the braces on the same line as its preceding token (I reformatted your code below). Also, I don't recall if this challenge is supposed to have a return value, so I removed that from the "func PlayHand" declaration.

Best of luck with Golang!

func PlayHand(score int) {
    if score < 17 {
        fmt.Println("hit me")
    } else if score > 21 {
        fmt.Println("bust")
    } else {
        fmt.Println("stand")
    }
}

Hi there! Jeff Muday is absolutely correct. And that's the reason it's giving you a compiler error. That being said, you'll need to take another look at the instructions to pass the challenge. It's not asking you to print anything but rather return the strings.

Good luck!

Remove the last return statement... it is causing your issue.

A better way to do this would be to declare a string at the beginning of the function which will be the action to take based on the score.

The if statement block covers all three cases. So we can set the action value there. And then finally, since you wanted the function to print the action, we do that in one statement. When I look to the earlier question, I see a requirement to RETURN a string, so in the very last line of the function we return action

func PlayHand(score int) string {
    var action string
    if score < 17 {
        action = "hit me"
    } else if score > 21 {
        action = "bust"
    } else {
        action = "stand"
    }

    fmt.Println(action)
    return action
}

Thanks Jeff & Jennifer!

I took on both of those feedback points and solved it pretty much straight away.

I was also stuck on the Switch Statements challenge - for exactly the same reason. So your feedback helped me to tick off both of those challenges (Y).

I am blocked, need help please ! Bummer! Expected a score under 17 to return "hit me" but got "..." instead.

package blackjack

import "fmt"

func PlayHand(score int) string {

    if score < 17 {
        fmt.Println("hit me")
    } else if score > 21 {
        fmt.Println("bust")
    } else {
        fmt.Println("stand")
    }

    return "..."
}

To assist, I would have to see more information on how PlayHand was called by the program. In addition, if you could reformat your code in a way I could see it all -- not all the code is inside the three backtick delimited blocks (see the Markdown cheatsheet). The reason why I stress this is GoLang is pickier than Java or C as to whitespace constraints.
