Trouble with an Objective-C print statement

Here's the question:

Using the printf function print the size in bytes of the variable real_numbers. Your output should look like the following: Array real_numbers is x bytes.

Here's my code:

float real_numbers[] = {11.11, 22.22, 33.33, 44.44, 55.55};

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

Hi Mark,

You have missed the word is and have an un-needed newline character at the end of your string.

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