You're asking a question that cannot be answered because much or
most of the program is in the two include files, which are not
shown.

As a general rule, when posting code there should be enough posted
so that readers can at least compile it.  In cases like the program
asked about here, what is posted should be enough to both compile
the program and run the generated executable.

The point is that what was posted is not enough to answer the
question of the Subject: line.

The Zebra Puzzle program has two version, a_puzzle_21.cpp (has
shown) takes too long to complete.  a_puzzle_2.cpp (736 lines, too
long to post, I thought) is the realistic one written in way I
feel just solving the prolem is enough.

I wrote a program in prolog to solve this puzzle.  The entire
program is 60 lines long, including 13 blank lines.  It finds
the solution in 0.03 seconds.  The program doesn't do anything
fancy;  it pretty much just gives the listed conditions in the form
of prolog rules, plus 20 lines to establish the structure of the
information that is being sought.
