# Problem 2: Advanced Arrays

## Task 1: Find the average cost!

Suppose we have an array containing the costs of various foods. Find the average cost of the food!

- You can use a
`for`

loop to go through the array! - Remember, the average of a list is the total divided by the number of items

## Task 2: Sorting an array!

The cost of each item in the menu is all over the place! Help us sort the array from least to greatest.

- Think of a way to sort the array (there are many different ways to do so)!
- Look at the example!

If we are given this array below,

```
int[] cost = {100,90,50,60,20,1,3};
```

we should get the following output:

```
int[] sorted = {1,3,20,50,60,90,100};
```

## Task 3: Make your own array! (optional)

Now it’s your turn! Input your own elements into the array!
