How many times does the while loop in the following code snippet run?

The code would not compile because you cannot use an int as a test in a while loop. It must be a boolean value.

zero time. x starts at $10,$ which is not the same as true. So the condition on the loop is false and it does not run.

This is an infinite loop as $x$ is always true since we created it on the first line.

$10$ times as $x$ reduces until it reaches zero which equates to false
