Yes, but in C too, when going from a[0] to a[N-1], people know there
are... (N-1)-0+1 elements (so, b-a+1). It is the same.

Now, why:

for(iterator from a[0] to a[N-1]){ //etc. }
//let use the above notation for for(i=0; i<=N-1; i++)

is acceptable, but sudden is no more acceptable to write

a[for(iterator from 0 to N-1)]

and one must use

a[for(iterator from 0 to N]]

in order to achieve exactly the same?

The last two expressions are just mental placeholders for a[0..N-1]
and for a[0..N] respectively.

I don't see that ground. Maybe I simply lack information. Can you
help?
