Final answer:
An enhanced for loop, or for-each loop, is used for iterating over arrays or collections without manually managing an index, making code cleaner and reducing errors.
Step-by-step explanation:
An enhanced for loop, also known as a for-each loop, is a simplified version of the traditional for loop that is used for iterating over arrays or collections in programming languages like Java, C#, and Python (using the 'for-in' syntax). Instead of manually managing an indexing variable and loop conditions, the enhanced for loop automatically iterates over every element within an array or a collection, assigning the current element to a specified variable.
This makes the code cleaner and less prone to errors related to the loop's indexing and condition management. For example, in Java, you would use for (dataType item : arrayOrCollection) { /* actions using item */ }, where dataType represents the type of elements in the collection or array, item is the loop variable that holds the current element, and arrayOrCollection is the array or collection being iterated.
