useful for constructing an array of fixed length buffers, where the length
is decided at run time. It is also useful as a data member of a base class
in a thin template class/base class pair where the type of the array element
is not known until the owning thin template class is instantiated.</p> <p>For
example, to implement a stack of fixed length objects of type <codeph>T</codeph>.</p> <codeblock id="GUID-F707A19F-A9C0-5704-973B-11A0087F714D" xml:space="preserve">class CExampleBase : public CBase
