What would be the value of this expression !(13%7 == 24%9)?
Why not test it and see? "really quickly". Either that, or do simple maths and simple logic.
!6 == 6) evaluates to !TRUE or FALSE.
With all the things to learn in programming, why is this kind of trivia seen as important, though?
Not always needed, but logical expressions like this should be grouped by their own parenthesis:
!((13%7) == (24%9))

Go figure....
I am going to guess he could not test it because this person was IN a test and didn't have access to the computer, but did have access to his iPhone/Blackberry/other handheld. Hence the "really quick" subject. If that's the case I hope the cheater failed.
Wouldn't they say phones... are not allowed during a test?
Sure. But they usually allow you to go to the toilet. My university puts alarms in the toilets though, that sound when they pick up mobile signals. Many people have been caught that way :)Quote:

Notice the bluster over the 0.03% detection rate.
I wonder what that actual undetected cheating rate is.
