Arrays
Arrays are fundamental data structures that store a collection of elements, typically of the same data type, in contiguous memory locations, allowing efficient access via indices. They provide a way to organize and manipulate multiple values under a single variable name, with operations like insertion, deletion, and traversal. In programming, arrays are essential for handling lists, matrices, and other sequential data.
Developers should learn arrays because they are a core concept in computer science, used in virtually all programming languages for tasks like storing data sets, implementing algorithms (e.g., sorting, searching), and managing collections in applications. They are particularly useful when the size of the data is known in advance and random access by index is required, such as in image processing, game development, or data analysis.
