Getting array length

I'm trying to complete the challenge with the following code but it keeps failing.

An output of the array length would be the right answer.

float real_numbers[] = {1.1, 2.2, 3.3, 4.4, 5.5};

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

Nevermind. I was missing a closing parenthesis.

Hi Jamie,

You're missing the closing parenthesis on your printf call.

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

Also, you're not showing the printf from the second task. I don't believe it will pass if you have taken that out.

Thanks. I had noticed the closing parenthesis but didn't know it still needed the previous answer. Thanks!

You're welcome. In general, you want to always keep previous code in place.
