# strlen
|
||
|
|
||
|
## Instructions
|
||
|
|
||
|
- Write a function that counts the characters of a string and that returns that count.
|
||
|
|
||
|
## Expected function
|
||
|
|
||
|
```go
|
||
|
func StrLen(str string) int {
|
||
|
|
||
|
}
|
||
|
```
|
||
|
|
||
|
## Usage
|
||
|
|
||
|
Here is a possible [program](TODO-LINK) to test your function :
|
||
|
|
||
|
```go
|
||
|
package main
|
||
|
|
||
|
import (
|
||
|
"fmt"
|
||
|
piscine ".."
|
||
|
)
|
||
|
|
||
|
func main() {
|
||
|
str := "Hello World!"
|
||
|
nb := Piscine.StrLen(str)
|
||
|
fmt.Println(nb)
|
||
|
}
|
||
|
```
|
||
|
|
||
|
And its output :
|
||
|
|
||
|
```console
|
||
|
student@ubuntu:~/piscine/test$ go build
|
||
|
student@ubuntu:~/piscine/test$ ./test
|
||
|
12
|
||
|
student@ubuntu:~/piscine/test$
|
||
|
```
