## pointone
|
|
|
|
### Instructions
|
|
|
|
- Write a function that takes a **pointer to an `int`** as argument and gives to this `int` the value of 1.
|
|
|
|
### Expected function
|
|
|
|
```go
|
|
func PointOne(n *int) {
|
|
|
|
}
|
|
```
|
|
|
|
### Usage
|
|
|
|
Here is a possible program to test your function :
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
"piscine"
|
|
)
|
|
|
|
func main() {
|
|
n := 0
|
|
piscine.PointOne(&n)
|
|
fmt.Println(n)
|
|
}
|
|
```
|
|
|
|
And its output :
|
|
|
|
```console
|
|
$ go run .
|
|
1
|
|
$
|
|
```
|
|
