The real reason is that you start with an offset of zero as you read an array from memory at hardware level, and so this way address is just “start address + element size * element number”.
minus-squareBorgDrone@lemmy.onelinkfedilinkarrow-up4·edit-21 year agoNo, we start counting at one. We start indexing at zero. An array with one element has an element count of 1, and that element would be at index 0.
