Why place i++ infront of println?

in the while loop index++ after println but now why is i++ before println and it's outside the curly brackets?

The for loop looks a bit different but functions exactly like the while loop in the video. They do the same thing. So you have: for index; condition; increment {code here}. The index variable is set, the condition is checked, and then the code is run. After the code is run, the increment takes affect, the condition is then checked again, and this process repeats until the condition is no longer True.
