Why are arrays usually processed with for loop?

The real power of arrays comes from their facility of using an index variable to
traverse the array, accessing each element with the same expression a[i]. All the
is needed to make this work is a iterated statement in which the variable i serves
as a counter, incrementing from 0 to a.length -1. That is exactly what a loop does.
