float real_numbers[5];

                   printf("Array real_numbers is %ld bytes.\n", sizeof(real_numbers));

                    printf("Array real_numbers can store %ld items.\n", sizeof(real_numbers)/sizeof(float));

you were missing the first line of code i think you the treehouse compiler is not that smart . but your code was good .

Wow, sorry, I thought that asking the question would link to the problem...

Here is the code challenge:

Print the length of the array real_numbers using the sizeof() function. Your output should look like the following: Array real_numbers can store x items.

The only thing different in your post is the \n new line character.. Would this really cause the code challenge to reject my answer?

Ugh, Figured it out.. I was changing the answer to question 2... Thanks!
