About this document
Understanding Arrays in Programming is a document available to read on EtoBox.
An array is a data structure that stores a group of elements of the same type in contiguous memory locations that can be individually accessed via indices. A two-dimensional array stores rows and columns of data, where each element is accessed by its row and column number. Arrays are easier to use than individual variables because they allow accessing multiple related values using indices, rather than needing separate variables for each value.
