# need some clarification

i am not to sure what the [points] instance is for?? I don't understand what it means. i see it implemented in our other classes we have made and am confused because i do not know what it means. can someone please help and explain

objects.swift
```// Enter your code below

struct Point {
let x: Int
let y:Int
///Returs the surrounding points in range of
/// the current one
func points(inrange range: Int = 1) -> [Point]  {
var results = [Point]()

let lowerBoundOfXRange = x - range
let upperBoundOfXRange = x + range

let lowerBoundOfYRange = y - range
let upperBoundOfYRange = y + range

for xCoordinate in lowerBoundOfXRange...upperBoundOfXRange {
for yCoordinate in lowerBoundOfYRange...upperBoundOfYRange{
let coordinatePoint = Point(x: xCoordinate, y: yCoordinate)
results.append(coordinatePoint)
}

}

return results

}
}
```

PLUS

This is an array that holds objects that are of a type "point"

```[points]
```

Its contents would look like this.

```var pointOne = Point(x: 2, y: 4)
var pointTwo = Point(x: 3, y: 5)
var pointThree = Point(x: 5, y: 6)

var points : [Point] = [pointOne, pointTwo, pointThree]
```

This is not unlike when we declare an array of objects of type "Int".

```var intArray : [Int] = [1,2,3,4]
```
