Something is wrong with the compilation...

Hello,

Im trying to submit my answer about this topic, but im getting two errors even if haven't changed anything in my code. 1) Tells that the creation of the array isn't correct 2) "Did your remember to declare a float variable called average and does not init it"? (or something like that)

Im quite upset 'cause I wrote the next code in my xcode project and works...

I don't really know what to do... please help!

the code is:

NSArray *temps = [NSArray arrayWithObjects: [NSNumber numberWithFloat:75.5], [NSNumber numberWithFloat:83.3], [NSNumber numberWithInt:96],/ I've tried with numberWithFloat too*/ [NSNumber numberWithFloat:99.7] ,nil]; float average;

variable_assignment.mm 
NSArray *temps = [NSArray arrayWithObjects:
                  [NSNumber numberWithFloat:75.5],
                  [NSNumber numberWithFloat:83.3],
                  [NSNumber numberWithFloat:96],
                  [NSNumber numberWithFloat:99.7],nil];
float average;
