To make is more complicated make that:

     int y = f (x);

And here in Ada you can have:

           int v [y];

Note that C99 supports this construct as well, however there is only one
compiler that implements this particular feature.

And yes I know about vector<> - in fact Ada has a generic Vector class as
well.
