Hi Darwin,

You simply forgot your "is". Here is what the print should look like

printf("Array real_numbers is %ld bytes", sizeof(real_numbers));

I hope that helps :)

for this one that ask Print the length of the array real_numbers using the sizeof() function. Your output should look like the following: Array real_numbers can store x items.

I got this its alright or am I missing something?

printf("Array real_numbers can store %ld items", sizeof(real_numbers) );

For this question it wants you to divide the real_numbers by the float size

printf("Array real_numbers can store %ld items.\n", sizeof(real_numbers)/sizeof(float));

this is a bug of whatever, I got the same situation my answer is :

float real_numbers[5] = {1.1, 2.2, 3.3 ,4.4 ,5.5}; printf("Array real_numbers can store %ld items", sizeof(real_numbers)/sizeof(float));

any I went xcode verified its bugfree.... but still : [Oops! It looks like Task 2 is no longer passing.]
