2-D Arrays

Now we have moved on to the most interesting thing! What is a **two-dimensional array**?

In the general case, two-dimensional arrays are called **matrices**: such mathematical structures that consist of **rows** and **columns**. If it will be easier for you, then you can represent the matrix as a table.

Now is the time to practice with 2D arrays.
Let's take a look how to create a 2-D array which contain such two arrays as `5.2, 3.0, 4.5`

, and `9.1, 0.1, 0.3`

:
