did you leave the code for task 2 in there as well? you need to have the code for all 3 tasks present in order to pass. your code for task 3 is correct, however you are missing the code from task 2.

you need to have

float real_numbers[5];
printf("Array real_numbers is %ld bytes.", sizeof(real_numbers));
printf("Array real_numbers can store %ld items.",sizeof(real_numbers)/sizeof(float)); 

Thank you for helping.
