## strlenprog

|

|
### Instructions
|
||
|
|
|
||
|
|
- Write a program that counts the characters of a `string` and that returns that value.
|
||
|
|
|
||
|
|
- If the program receives more than one `string` or no arguments must not return anything (see the `Expected output`).
|
||
|
|
|
||
|
|
### Expected output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/piscine-go/strlenprog$ go build
|
||
|
|
student@ubuntu:~/piscine-go/strlenprog$ ./strlenprog "hello"
