This is primarily the actual answer. While most languages force you to see the array as an array, in C/C++ (in C++ I'm only referring to the memory allocated variable type, not an "array class") you can see it as a pointer and do your own math to address any part of it that you want. And the calculation for that memory address is idx * sizeof(the thing in your array). So the real answer here is that array semantics needed to match memory address semantics in the languages that provide that.
