Arrays and Sorting

As a developer, you have certainly stored various collections within your applications, such as data of users, books, and logs. One of the natural ways of storing such data is by using arrays. However, have you ever thought about their variants? For example, have you heard about jagged arrays? In this chapter, you will see arrays in action, together with examples and detailed descriptions.

You can use an array to store many items of the same type, such as int, string, as well as a user-defined class or record.
