How do you scan many number you don't know their count?

To scan an unknown number of items, you can use a loop that continues until a specific condition is met, such as reaching the end of input (EOF) or when the user indicates they have finished entering numbers (e.g., by entering a sentinel value like "done"). In programming languages like Python, you might utilize a while loop with input() to continually read numbers until the termination condition is triggered. You can store the scanned numbers in a list or another data structure for further processing.
