minus-squaremacniel@feddit.delinkfedilinkarrow-up5·1 year agoNo. We count start at zero because the array already starts with an element of a specific size. Starting at 1 would always skip that initial element.

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-squareBorgDronelinkfedilinkarrow-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.
