Creating an Array Literal

We learned one way to create an array, but there’s another.

We can also declare and initialize an array with a list of values, separated by commas, and surrounded by a pair of square brackets.

The syntax to create an array this way looks like:

``var name = [list of values]``

Suppose we want to create an array called `location` with Codecademy HQ’s latitude and longitude:

``var location = [40.7245, -73.9979]``

Due to Swift’s built-in type inference, the type of the array is inferred. To be explicit:

``var location: [Double] = [40.7245, -73.9979]``

Let’s try creating arrays using this new approach.

### Instructions

1.

Suppose the Tokyo Subway costs are as follows:

24-hour ¥800 ¥400
48-hour ¥1200 ¥600
72-hour ¥1500 ¥750

Create an array named `subwayAdult` and initialize it with `800`, `1200`, and `1500`.

Print it out using `print()`.

2.

Initialize `subwayChild` with `400`, `600`, and `750`. This time, be explicit with the type.

Then print it out.
