Array Challenge part 3 problems

Question: 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.

My reply:

float real_numbers [5] = {}; printf("Array real_numbers is %ld bytes./n", sizeof(real_numbers)/sizeof(float));

This is racking my brain. Any clues as to what I'm doing wrong at this point? Thanks in advance.

I had the same issue with this one, but finally figured it out. It checks to make sure task 2 works as well as task 3. So your code should look like this,

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(real_numbers)/sizeof(float));

it could be the fact that you initialized it as an empty array. maybe try just declaring it like so:

float real_numbers[5];

or it could be your string. Make sure your string is EXACTLY as asked for in the challenge. does the challenge want a period on the end?

Thanks, gentlemen. Looks like it was still looking for the the second print statement along with the question asked (as Alex pointed out). Guess I wasn't expecting to carry over the second statement. Ooops.
