Use NSLog to print out the value of the variable 'thing'. The output should look like: "thing = 4".

Stage six quiz question 3/3: "Use NSLog to print out the value of the variable 'thing'. The output should look like: "thing = 4"."

I am completely stuck on this. Not sure why. An NSLog shouldn't be that difficult, but Im stuck. My previous code for this:

id thing = nil; thing = @4;

Try this: 

NSLog (@"thing = %@", thing);

if that thing variable is a number then the following should work: NSLog(@"thing = %d",thing);

^^^ Nope that didnt work either. Previous questions in quiz: (1)"Declare a variable named "thing" to type id and initialize it to nil." Which was id thing = nil; (2)"Assign an NSNumber literal with a value of "4" to the variable "thing." Which was thing = @4;
