It's a standard formatted for-loop. It's creating the integer variable i, and setting it to zero. The second part is saying "do this while i is less than 10", and the last part is saying what to do after the loop runs once -‐ increment i by 1. Under this would be the actual stuff you want to be doing in that loop. Assuming nothing in the rest of the code is manipulating i, it'll do this 10 times and then move on
