Another way of getting data back from a function to the
calling program is by using pointers which we will cover in
the next chapter. When we get there we will find that an
array is in reality a pointer to a list of values. Don't
let that worry you now, it will make sense when we get
there. In the meantime concentrate on arrays and understand
the basics of them because when we get to the study of
structures we will be able to define some pretty elaborate
arrays.
