Questions tagged [arrays]

An array is an ordered data structure consisting of a collection of elements (values, variables or references), each identified by one or more indexes. When asking about specific variants of arrays, use these related tags instead: [vector], [arraylist], [matrix]. When using this tag, in a question which is specific to a programming language, tag the question with the programming language being used.
