How can X[i] possibly be interpretted the same as i[X] in C?

I think the question is asking how an array[elementInArray] can be interpretted the same as elementInArray[array]

Also, unrelated on the same homework: "Explain why the "hidden bit" of floating point format does not need to be represented." (in terms of 32 bit words of binary)

You have two unrelated questions here. You should split them. But the first one is a duplicate and the second one can probably be easily googled. — Mysticial, Oct 25 '12 at 07:27

In C, X[i] = i[X] = *(X + i) = *(i + X). As per commutative property, they are same.
