MFC extension class CBitArray

Environment: Visual C++ 6, Windows 95/98/Me/NT/2000/XP

The class CBitArray behaves like a specialization of the MFC template class CArray. A real specialization is not possible because of a missing simple data type for a bit.

For maximum efficiency the bits are packed into a dynamic array of unsigned longs. You can easily modify the type of the date containing the bits (see typedef ULONG T in the declaration of CBitArray). CBitArray implements all member functions of the MFC class including the operator function [] (both for l-values and r-values).

The private member functions Copylr, Copyrl, and X are derived from the same-named functions of the class bitstring written by P.J. Plauger and are published with permission of the author.
