 ## Arrays
 
 Working with data is a common task for any language, and it's a much easier task when data is organized in a structural format, such as arrays. With arrays, data is stored in a structure similar to a list. One major benefit of arrays is that you can store different types of data in one array.

 ## Arrays
 Trabalhar com dados é uma tarefa comum para qualquer língua, e é uma tarefa muito mais fácil quando os dados são organizados num formato estrutural, tal como as matrizes. Com arrays, os dados são armazenados numa estrutura semelhante a uma lista. Uma grande vantagem dos arrays é que se pode armazenar diferentes tipos de dados numa única matriz.
