Data Structure Arrays Interview Question:

What is keyed array data structure?

Submitted by: Ali

A "Keyed Array Data Structure" is an array data structure with one subfield identified as the search or sort key. The array data structure is indexed by (*) and followed by the specification of the key subfield. For example, consider array data structure FAMILIES with one scalar subfield NAME, and another array subfield CHILDREN. To use the FAMILIES data structure as an array data structure keyed by NAME, specify FAMILIES(*).NAME. To use the first CHILDREN element as the key, specify FAMILIES(*).CHILDREN(1).
