print(i)
}
// 1
// 2
// 3
```

### Half-open range used on an array

```
let players = ["Ayesha", "Beatrix", "Chris", "Daisy"]
for i in 0..<players.count {
print("Player \(i + 1) is \(players[i])")
}
// Player 1 is Ayesha
// Player 2 is Beatrix

let players = ["Ayesha", "Beatrix", "Chris", "Daisy"]
print(players[2...]) // ["Chris", "Daisy"]
print(players[...2]) // ["Ayesha", "Beatrix", "Chris"]
