iOS Objective-C Basics (Retired) Fundamentals of C Operators & Expressions

Im taking a quiz on operator expressions and i feel like the quiz has nothing to do with what i just learned.

I cannot pass this quiz because it has nothing to do with what i just learned. it is asking questions that i have no idea what they are telling me to do and i have gone back and watch the video multiple times.

I'm only starting to take the quizzes but I think if you've skipped a quiz or moved ahead to another video, it may be backdating your quiz questions to a previous section?

Are the questions in the quiz even related to the right track/topic?

yes but the way they are written makes no sense to me. I have gone back and watched the video 10 times now and what he explains to do has seemingly nothing to do with the questions or the way the questions are written make no sense to what we just learned.

How would you declare an integer variable named unstable and initialize it 25?

_____________ unstable = __________;

int unstable = 25

Auto increment the variable named unstable:

int unstable = 25; unstable -= 5;

i tried " unstable += 5; " also, " unstable ++=5; "

and that was wrong, so what am i doing wrong here , any help is appreciated

int unstable = 25; unstable -= 5; unstable++;

int unstable = 25; unstable -= 5; unstable++; unstable--; unstable ________ 3;

i have no idea what to do with any of these

What course are you doing and up to what stage have you viewed the videos for? I'll try help you figure this out.

When you go to your home page, and navigate to your course page, you should see a list of stages and items such as videos, quizzes etc marked with various icons.

As you progress through the course these icons turn green. Can you see if any of the bullet icons are not green or seem to have been skipped?

Actually, a better question might be, when you're taking the quiz, select the Review video button. Is the video that appears the same video that you just watched?

I just watched the first couple of minutes there and it seems to be the right one...?

it is the right video, i just dont understand how to answer the questions then. to me what the video has me do and what the questions are asking are night and day. i am just lost

it is int unstable 25
