Arrays

Arrays are fundamental data structures in programming that store a collection of elements, typically of the same data type, in contiguous memory locations. They allow efficient access to elements via numerical indices, making them essential for organizing and manipulating ordered data in algorithms and applications.

Also known as: Lists, Vectors, Sequences, Indexed collections, Static arrays

Why learn Arrays?

Developers should learn arrays because they are ubiquitous in programming for tasks like storing sequences of data, implementing algorithms (e.g., sorting, searching), and handling collections in memory. They are used in scenarios such as processing lists of items, managing buffers, and building more complex data structures like matrices or stacks.
