Final answer:
The while loop in the C++ program will print the numbers 10 to 0 in descending order, one per iteration.
Step-by-step explanation:
The student's question is about what will be printed by a loop in a C++ program. The given code snippet is a while loop that decrements the variable x from 10 to 0, printing each value before decrementing. The loop checks the condition x >= 0 before each iteration. The output printed by this loop would be the following sequence of integers: 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0. Each number would be printed on a separate line if a line break is automatically inserted after each cout operation or adjacent if not.
