I'm trying to learn Go and I've created a function where I declare a variable game_ratio and set it to 0.0. I then have an if statement where I try and update the value of game_ratio. When I try and compile, I get the following error message: 'game_ratio declared and not used'
Here's my function:
func gameRatio(score1 int, score2 int, max_score float64) float64 {
var game_ratio float64 = 0.0
var scaled_score_1 = scaleScore(score1, max_score)
var scaled_score_2 = scaleScore(score2, max_score)
fmt.Printf("Scaled score for %v is %v
", score1, scaled_score_1)
fmt.Printf("Scaled score for %v is %v
", score2, scaled_score_2)
if score1 > score2 {
game_ratio := (scaled_score_1+1.0)/(scaled_score_1+scaled_score_2+2.0) + 1.0*0.5
}
return game_ratio
}
Here's the code to call it:
func main() {
flag.Parse()
s1 := flag.Arg(0)
s2 := flag.Arg(1)
i1, err := strconv.Atoi(s1)
i2, err := strconv.Atoi(s2)
if err != nil {
fmt.Println(err)
os.Exit(2)
}
fmt.Println("Game ratio is", gameRatio(i1, i2, 6))
}
ScaleScore is another function I have written. If I remove the if statement, the code works.
To run my app, I type 'rankings 28 24'
