## isalpha
|
|
|
|
### Instructions
|
|
|
|
Write a function that returns `true` if the `string` passed as the parameter only contains alphanumerical characters or is empty, otherwise, and returns `false`.
|
|
|
|
### Expected function
|
|
|
|
```go
|
|
func IsAlpha(s string) bool {
|
|
|
|
}
|
|
```
|
|
|
|
### Usage
|
|
|
|
Here is a possible program to test your function :
|
|
|
|
```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"))
|
|
|
|
}
|
|
```
|
|
|
|
And its output :
|
|
|
|
```console
|
|
$ go run .
|
|
false
|
|
true
|
|
false
|
|
true
|
|
$
|
|
```
