"Iterator" Pronounce,Meaning And Examples

"Iterator" Meaning

An iterator is a control structure that enables traversing or processing all elements of a container, such as an array or a linked list, in a single pass. Despite their similarities in spelling and structure, an iterator is different from aenumerator. While an enumerator returns each element in an ordered sequence, an iterator returns elements one at a time in possibly non-ordered manner. Iterators are useful when you need to process a collection of items in a loop, performing some operation on each item without having to worry about the underlying structure of the collection.
