Array Allocation

[Timothy Scully <trs2@kent.ac.uk>]

I am trying to allocate a variable array, using the float_Array Object.
The code I am using is simply to create an array pointer but then to use
the Alloc function. However this gives me an expected NULL pointer
error. How do I create a new float_array, do I have to create it as a
child of the root object ?

Code:

float_Array *farr;

farr.Alloc(10);

// error occurs.
