An Array is a data structure used in programming to store a fixed-size, ordered collection of elements, all of the same data type. Each element in an array is identified by its index, starting from zero, which allows for quick and direct access. Arrays are commonly used to organize data in a linear format—such as lists of numbers, characters, or objects—and support operations like searching, sorting, and iterating. They are foundational in many programming languages including C, Java, Python, and JavaScript, and serve as the basis for more complex data structures.
