Arrays

An array is a way to organize a group of items in rows and columns, like a table.

You can count items in an array by counting each row and each column.

The first row is the top row of the array.

The last column is the far-right column of the array.

Multiply the number of rows by the number of columns.

To arrange items means to put them in a specific order in rows and columns.

No, all rows in an array must have the same number of items.

A 2D array is an array that has two dimensions: rows and columns.

An example is: Row 1: A, B, C; Row 2: D, E, F.

Arrays help organize data so it is easier to understand and use.
