Filling Out the Array 3D Data Structure

The <Array_3D> class is the generic base class that underlies all the other <Array_3D_* > classes. Use it when one of the more specialized classes is not appropriate and you don't need access to any software developed specifically for them.

For an Array_3D, follow the instructions for Filling Out the Array_2D Data Structure, with the following additional constraints/requirements:

• Use <Array_3D> and </Array_3D> rather than <Array_2D> and </Array_2D>

• <axes> must have a value of 3, rather than 2.

• There must be three <Axis_Array> classes, rather than two.
