What occurs to the loop variable after examining an item in a loop?

In a loop structure, the loop variable serves as a placeholder that represents the current item being processed in the iteration. After examining an item, the loop variable is updated to reflect the next item in the collection being iterated over.

The process of copying field values for the next item into the loop variable enables the loop to dynamically refer to and work with each item in succession. This allows operations within the loop to access properties or manipulate data relevant to the current item effectively.

While the loop variable is essential for referring to the item currently being processed, it retains its role in each iteration. After one iteration concludes, the loop mechanism updates this variable with the content of the next item in the sequence, ensuring that the loop can continue processing without interruption. This functionality is key to iterating through data collections correctly and efficiently.
