Answer:
The solution code is written in Python:
Explanation:
Firstly, we create a variable itemsOSS (intialized it with empty string) and use it as output string stream (Line 1).
Next use input function to prompt user to enter first item (Line 2)
While the item value is not "Exit" (Line 4), append userItem to variable itemsOSS.
When the user enter "Exit", use print function to print the itemsOSS string (Line 8).
