How would declare the following instance if you didn't know which class it belongs to?

This is a quiz question within the "Designated Initializers & Convenient Constructors" section of "Building A Blog Reader App for iPhone." I am running up against a wall; perhaps it's something simple I am overlooking but can't even find a hint in my notes.

Here is the question:

How would declare the following instance if you didn't know which class it belongs to?

obj = [1,2,3,4];

When declaring a variable you don't use parenthesis. The parenthesis are used only when declaring the return type to a method.

id obj =  [1,2,3,4];

Thanks Amit ! Another quick question, when i see your answers in here they are coloured etc. When doing the code challenges and quiz mine is in black and white, and doesn't auto complete.

I am assuming that everyones is like this ? and the auto complete only works in Xcode ?

thanks.

Yes, unfortunately the autocomplete is only available in Xcode and we are working on better syntax highlighting for Code Challenges. So don't worry this is not just you this is how our site behaves for everyone.
