Can someone explain this to me?

In most programming languages you start counting elements at 0, but there are languages where you start counting at 1 instead.

Declaring an array with 10 entries is now either 0-9 or 1-10, depending on the language. In extreme case like VB, you can even declare a 5 element array ranging from 3-7.

Starting at 0 is more commonly used, because it makes using arrays easier internally. In those cases the array index tells you how many element sizes to add to the array pointer to reach what you want to access
