     C will pass the address of the first element of the array to the function,
which will be expecting an address. So, in general you can:

         call_f(array[10]) <-- I wonder if the 10 is really required here...
                                 but it works for me on Turbo C.

         void call_f(array[]) <--Notice no 10. The function is only expecting
the address of the beginning of the array. You can still do array[0]++ or
something, but be careful not to reference the array outside of it's
initially declared bounds (remember, an array of 10 goes from 0 to 9!).
