I'm not understanding this. How's num used here??

Answer 1

num is a variable here used to control the loop. In other words the value of 'num' variable will decide whether the code inside loop will execute or not as after each execution the value of num is increasing by 1 so the loop will not continue to run after a specific number of executions.
