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

array can store x items

I don't what I'm missing? it's asking me to find How many real_number can the array hold?

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 (float) / sizeof(real_numbers));

array_length.mm
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 (float) / sizeof(real_numbers));
