My understanding is that void is used before a method that will not return a result. But it's also used in front of methods that are doing a calculation, and definitely returning a result. Where am i misunderstanding this?

If you were to use a horizontal line and want to make it a certain color, how would you also make its width different? I can't wrap my head around THIS one. for example: --<HR COLOR="#00FF00"/> This makes it green, but I can't add width in there. is there some certain way?

so far in section 1 question 2 area all of the videos have been ads that if you skip the add it just brings up the questions you need to answer. also if you play the add all the way thru you get the same exact thing. luckily I'm using this as a refresher course but I would think if I didn't know anything about c++ then I could be pretty lost missing videos.
