# isalpha
|

|
|
|
||
|
|
## Instructions
|
||
|
|
|
||
|
|
Écrire une fonction qui retourne `true` si la `string` passée en paramètre contient seulement des caractères alphanumériques, et qui retourne `false` autrement.
|
||
|
|
|
||
|
|
## Fonction attendue
|
||
|
|
|
||
|
|
```go
|
||
|
|
func IsAlpha(str string) bool {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Utilisation
|
||
|
|
|
||
|
|
Voici un éventuel [programme](TODO-LINK) pour tester votre fonction :
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
piscine ".."
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
fmt.Println(piscine.IsAlpha("Hello! How are you?"))
|
||
|
|
fmt.Println(piscine.IsAlpha("HelloHowareyou"))
|
||
|
|
fmt.Println(piscine.IsAlpha("What's this 4?"))
|
||
|
|
fmt.Println(piscine.IsAlpha("Whatsthis4"))
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
Et son résultat :
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/piscine/test$ go build
|
||
|
|
student@ubuntu:~/piscine/test$ ./test
|
||
|
|
false
|
||
|
|
true
|
||
|
|
false
|
||
|
|
true
|
||
|
|
student@ubuntu:~/piscine/test$
|
