iOS Objective-C Basics (Retired) Fundamentals of C Arrays

Array syntax

In the video on Arrays, the instructor declares an array: float numbers-geeks_love[ ] = {3.145, 1.618, 1.4142};

When I attempt to declare an array in the exercise, it says I must declare the number of elements in the brackets [3]

When I tried it with a number in the brackets, I got the same error message.

I opened Xcode an tried it without the number inside and it compiled and ran fine.

Any explanation?

Hi Art! Could you post your code? Maybe I can help you out.

If I remember correctly, the challenge asked you to create an array large enough for three items. That's all! You don't need to put items in the array - it should stay empty.

Re-read the directions and follow them exactly. Typically, the challenges are simpler than you expect. (Please note: I didn't say easier, I said simpler. Sometimes I find it harder to only right the code the challenge asks for...)
