Is there a specific reason for arrays to start at 0?

Question

Why is it that arrays always start at 0? Is there a specific reason?

Answer 1

Because the first address where the array starts in memory is where is the element is. So if you take the address of the whole array + 0, you get the first element stored in the array.

Answer 2

Well, kinda. The usual names for the states a single bit can have are usually called 0 and 1. So 0 is the smallest possible value.

There are programming languages that start at 1 though.

Answer 3

In programming zero doesn't mean nothing, it's a value . NULL is nothing .
