What is wrong here?

I have looked at this for awhile and see no error here, is there something I am missing? Thanks! Task: 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.

" float real_numbers[5]; printf("Array real_numbers is %ld bytes", sizeof(real_numbers)/sizeof(float));"

Hi,

there is nothing wrong with your code. The problem is that you are not answering the question. Your code returns the number of items in the array and not it's size.

Use:

float real_numbers[5];
printf("Array real_numbers is %ld bytes", sizeof(real_numbers));

Oh okay got it, I must have read the question wrong. Thanks for your help!
