Objective C Stage 3: Question Set 1, Question 2

in my Xcode, I run the following:

float real_numbers[] = { 1.11, 2.22, 3.33, 4.44, 5.55 }; printf("real_numbers is %ld bytes\n", sizeof(real_numbers));

and it works,

however in the online questions -- it tells me that it's not correct. My xcode displays it in the debugger showing real_numbers is 20 bytes which is the correct answer ( float is 4, 5 numbers... 5*4 = 20 )

I figured this one out. The issue was in the fact that in the printf statement I was missing the word "Array" at the beginning. Everything else was correct.
