Stuck on Array size & length challenge

This is what I've got float real_numbers [] = {1, 2, 3, 4, 5 }; printf("Array real_numbers is %ld. bytes\n", sizeof(real_numbers)/sizeof(float));

and it says its not correct

Are you on task 2?

For task 1 you don't have to initialize the array with values but it doesn't hurt. You can pass with float real_numbers[5]. You are simply declaring an array to have room for 5 floats.

For task 2, they want to know the size of the array. So that's sizeof(real_numbers). That gives you the total size of the array. Which is how much space 5 floats would take up.

I did initialize task 1 with values but after shortened it I was able to pass task too... although my previous statement ran fine in xcode....
