# swap
|
||
|
|
|
||
|
|
## Instructions
|
||
|
|
|
||
|
|
- Write a function that swaps the contents of two **pointers to an int** (`*int`).
|
||
|
|
|
||
|
|
## Expected function
|
||
|
|
|
||
|
|
```go
|
||
|
|
func Swap(a *int, b *int) {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Here is a possible [program](TODO-LINK) to test your function :
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
piscine ".."
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
a := 0
|
||
|
|
b := 1
|
||
|
|
piscine.Swap(&a, &b)
|
||
|
|
fmt.Println(a)
|
||
|
|
fmt.Println(b)
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/piscine/test$ go build
|
||
|
|
student@ubuntu:~/piscine/test$ ./test
|
||
|
|
1
|
||
|
|
0
|
||
|
|
student@ubuntu:~/piscine/test$
|
||
|
|
```
