On a scale from 0 to 1

How based are your arrays?

>>7
You're assuming data is a point, when in fact it spans from beginning to end. And array element are accessed by the address of the beginning. The FIRST element is the one that goes from 0 to 1. The second goes from 1 to 2. And so on.

The first element of an array is the address of the array+0
or Array[0] or *(Array+0). That was the rationale for 0-based arrays.

Maps aren't contiguous structures, arrays are. Your argument is invalid.

Relative position to the pointer which points to the first element.
