An array is a data structure in computer science that contains a collection of elements of the same data type. The elements are stored in a continuous storage area and can be accessed by an index that indicates at which position in the array the element is located.
The first element in the array usually has index 0. Arrays can have a fixed size, specified when the array is declared, or grow dynamically as needed during program runtime.
Arrays are often used to store and process data efficiently, especially when dealing with large amounts of similar data, such as images, audio or video files.
