An array is a collection of elements of the same data type stored in contiguous memory locations. Single-dimensional arrays hold a list of elements, while multi-dimensional arrays can be visualized as tables or matrices.

Arrays must be declared with a fixed size. Indexing starts at zero. Arrays allow efficient data storage and access via indices. They are widely used for storing large amounts of data such as lists or matrices. Memory for arrays is allocated at compile time for static arrays. Operations like traversing, updating, and searching are common with arrays.
