Nothing good, it seems. *grin* Basically, the context is roughly that of
a calendar. I wanted to call the tomorrow method, increment the two
aspects that get incremented every day (day of week and the day of the
month), then call a separate method to put the new date through all the
appropriate checks and fix any inaccuracies (roll over the month, roll
over the week, deal with February and Leepear, etc.). Since I sent that
out I realized I could just declare all the needed variables as private
data members "globally" in the class itself and not actually call the
method with any specific parameters. I just called the tomorrow method,
then the validation method with no parameters, but since all the
parameters I'd be working with were declared just within the context of
the class, the method that validated the accuracy of the date was able
to check and change them all as necessary. This way I could manipulate
all the integers in the MyDate class. Not sure how wise a solution that
is, but it seems to have kept me moving in the meantime.
The program itself is a project for class, aimed at working on the
implementation side of inheritance. The prof has admitted that
programatically it's not the way one would normally lay things out, but
as mentioned, he's trying to force us into a particular arena, so to
speak. If you want to see the whole story, I'd be happy to fill you in,
but I don't know if the list wants me to push that amount of code on
everyone's inbox. *grin* I do get though that my approach in this
situation of trying to essentially pass a primitive by reference was
probably not the smartest way to go. Hopefully this new wrinkle will
continue to be sufficient.
