number of items in array

The challenge asks for me to declare an array that will hold five floats. Since the array is 0-indexed, shouldn't the correct response be ```float real_numbers[4];

rather than 
```float real_numbers[5];

There's a difference between declaring an array of a certain size and accessing elements in that array.

They are zero based index but to create it you have to say how big you want it.

type arrayName [ arraySize ];
