The index refers to the position or location of an element within an array. It starts from 0 for the first element and increments by 1 for each subsequent element.
Looping Constructs: Looping constructs such as "for" loops or "while" loops are used to iterate over elements in an array repeatedly until certain conditions are met.
Element Access/Modification: When traversing an array, you can access or modify individual elements using their respective indices.
