iOS Objective-C Basics (Retired) Pointers and Memory Array Size and Length

Challenge task 2 of 3 doesn't work for me! For Objective-C Basics, topic Array Size and Length.

I have the following code:

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

And tested on my Xcode I got the output: "Array real_numbers is 20 bytes.",

which should be what the challenge is about. But when I tried to submit the work, I kept getting an error.

you have

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

you misspelled real_numbers as ream_numers

try

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