I'm having trouble with syntax error
NSArray *temps = @[@75.5,@83.3,@96,@99.7];
float average;
float runningTotal;
for (NSNumber in temps;) average = temps++; {
average = runningTotal /[temps floatValue];
}

NSArray *temps = @[@75.5, @83.3, @96, @99.7];
float average;
float runningTotal;
for (int i = 0; i < temps.count; i++) {
runningTotal += [[temps objectAtIndex: i] floatValue];
}
average = runningTotal / temps.count;

I just finished this exercise here and think I can help.
The for in loop you have there needs to have a named value. You can call it anything, but in mine below I called it 'tempItems"
NSArray *temps = @[@75.5, @83.3, @96, @99.7];
float average;
float runningTotal;
for (NSNumber *tempItems in temps) {
runningTotal += [tempItems floatValue] ;
}
average = runningTotal/temps.count;
Hope that helps!
