Courses Plus Student 299 PointsPrint function is giving me an error "size of" for array length
float real_numbers[] = {1,2,3,4,5}; printf("float %ld bytes\n" , size of (float));
it gives me an error that "size" is not declared. I don't understand. I took notes and that's how I was taught.

Courses Plus Student 94,610 PointsHi Renee,
You have a few errors with your code. sizeof
shouldn't have a space in it.
Also, it's asking for the size of real_numbers
not the size of a float
. real_numbers
is an array with enough space for 5 floats. So really what they're asking is what's the size of 5 floats.
One more thing is that your output string wouldn't match what it's asking for.
The output string should be in the form Array real_numbers is x bytes.
Your current output string looks like float x bytes\n
Let us know if you're still stuck.

Courses Plus Student 299 PointsThank you Jason for your insight. I did have a space between size of, so I corrected it to "sizeof" and it worked. The little things make a big difference when writing a code!
I appreciate your assistance! I'm new to Treehouse, so I apologize for not responding to your answer.

Courses Plus Student 94,610 PointsForgot to mention too that you don't have to initialize your array with 5 values. You only have to declare an array that will hold 5 values.
Putting in 5 numbers still passes but this will work too:
float real_numbers[5];
