561 PointsThe quiz is awful.
unstable ++; is wrong, because there is a space? WTF...

Treehouse Guest TeacherSorry about that, we realize that our fill in the blanks are a bit restrictive. It's on our radar to make them a bit more flexible in the near future.

561 PointsWell, the quiz says auto increment the variable "unstable", and "unstable++;" is right, "unstable ++;" is wrong.(there is a space)

561 PointsWell, it seems the code engine is not smart enough. "NSLog(string);" and "NSLog(@"%@", string)" is the same if string is an NSString* variable. But the code engine seems only take the latter as the right answer.

Courses Plus Student 1,984 PointsYour working with C not objective C in that quiz. printf And thinking back i think the same happened me in that quiz with the auto increment.
Heda Wang
561 PointsWell, NSLog takes at least one argument NSString *format. So if string is an NSString variable, "NSLog(string);" and "NSLog(@"%@", string)" give you the same output.

Courses Plus Student 1,984 PointsYou are doing the C tutorials
float fa = 5.0 / 0.5;
printf("fa %f\n", fa);
int unstable = 25;
unstable -= 5;
printf("unstable %d\n", unstable);
You do not need NSLog or NSString in that quiz

561 PointsOh, I know what you mean. I've commented under the wrong chapter.
But when I realize that there is a problem, I've already submitted. And once I submitted, there is no clickable discussion button.
John Carr
Courses Plus Student 1,984 PointsYes i saw what you meant on the auto increment i went and done that quiz again. If you want to start a new discussion just click on start discussion , click what topic - IOS and what your topic is - lets say NSLog and NSString
