How would I write the declaration statement for an array with 30 integers,

Would this be how?

```auto
int[] arr = new int[30];
int min = arr[0];
int max = arr[29];

```

min would be 0 and max 29 if you see them as index

Otherwise good

Test it yourself in processing

You can fill it in a for loop with random numbers

There is a tutorial about arrays
