Array Length

Why isn't my code allowing me to proceed?

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

Xcode displays the correct result "Array real_numbers can store 5 items."

array_length.mm 
float real_numbers[5]; 
printf("Array real_numbers can store %ld items.\n", sizeof(real_numbers)/sizeof(float));

The output from Treehouse is Bummer! Make sure you are calling printf and passing a string (not an NSString) and real_numbers as the parameters. The correct format option is '%ld'.
