array

array is a method for storing information where data is arranged in a collection of elements, each identified by at least one array index or key. It is a special variable that can hold more than one value under a single name. It is possible to then access the values by referring to an array index or key.

Arrays are commonly used in programming to organize data so that a related set of variables can be easily sorted and searched. For example, search engines use arrays to store pages found in a search performed by the user. When displaying the results, the program outputs one element of the array at a time. This may be done for a specified number of values or until all the values stored in the array have been output. Therefore, storing the results in an array is a very efficient way to manage memory.
