Problem declaring arrays

I have a question in regards to the problem being asked. It's asking to declare a float named real_numbers with an array of 5. I've typed up float real_numbers [] = {1,2,3,4,5} and got an error saying remember when saying how many there are you must state it in real_numbers[5]. Is it telling me to go the long way around? such as: float real_numbers[5] real_numbers[0] = 1.1 etc?

Thank you for all your help and explanation to my question.

array_length.mm 
float real_numbers [] = {1,2,3,4,5}

Hi Steven,

William's answer looks right to me.

Aside from this, however, you should really be taking this newer version of the Objective-C Basics course, rather than the one you're taking now.

Happy coding!

problem here is that the on step 1, the challenge only asks you to declare a 5-items float Array variable, but not assigning any values to it just yet.

float real_numbers [5];

This would be suffice. hope it helps.
