What's wrong with my syntax?

I'm trying to print the size (in bytes) of an array of floats of length 5. Here's my code:

float real_numbers[5]; printf("real_numbers is %ld bytes./n", sizeof(real_numbers));

Any ideas?

Your syntax appears to be correct. Make sure you're printing exactly what it tells you to though. It's looking for "Array real_numbers is %ld bytes.\n" versus what you wrote: "real_numbers is %ld bytes./n".
