Aha!  Yes, that information would have been quite useful and saved me
some time in the C -> C++ conversion.  I have learned my lesson and will
no longer try everything I know before asking for help.  I compiled
Klauke's original code, and ran it on game.5 (which is the file we were
working on yesterday). The output is result.5. I'm attaching all of his
code, and the input and output files. It would have been very difficult
to figure out how to use the program without fiddling with the code,
since none of it is documented, and the input order is not specified.

To compile the code, one must write:

g++ main.cpp nuk.cpp rand.cpp -lm

To run the program, the command is:

a.out x p

where x is the game number (it looks for a file called game.x), and p
(optional) is the precision (number of decimal places of calculation and
output -- note: program still uses double and float, so the true maximum
is the same 15 as the C version).

So to evaluate game.5, I enter: "a.out 5" where the default precision is
six decimal places. The solution (documented in a file called result.5)
seems to agree with what we had in the other code.

I think that the conversion time was not wasted, as it gave me an
opportunity to really dig into the program and understand its intricacies
and deficiencies. But yes, seems like it worked all along.
