The Loop is supposed to run 10 times, so you would put "10" in where it says blank.

Counter starts at zero and and increments +1 every time it goes through the loop.

It keeps running as long as it is less than 10.

Remember the first time the loop runs counter is 0.

So starting at 0 it runs 10 times.

0,1,2,3,4,5,6,7,8,9

Then when it gets to 10 it stops the loop because 10 is > counter.

Thanks,I appreciate u

If it has the requirement: Finish the code below so that the loop runs 10 times

then the blank should be 10. Since the while statement is < blank (not <=), and counter is initialized to 0, the loop will run with counter values 0-9 which would be 10 times.
