Declare an int property called qty

Let's declare an int property called "qty". (Remember qty is not an object so it should not have the strong attribute).

@interface Product : NSObject

___________ (____________) int qty;

@end

What is this question asking? I do not see anywhere from the videos before where this matches any syntax.

The question is asking you to declare a @property which can also include attributes for to define how it should be accessible or retained in memory. Check out the Objective-C docs on properties. If you still need some help let me know.
