Bus Pass Project

Hi,

I am in the process of implementing this in Prolog but have no prior
knowledge in the language and hoping someone will guide me towards the
right direction.

This is the situation:
Bus station that issues bus pass for a certain number of seats on a
particular bus schedule.
anyone can purchase them.
The passenger can also pass his/her pass to others. That case, they
loose the right to board the bus but the new person should be allowed
to board the bus.
when they enter the station, with a valid pass, the station should
allow them to use the bus
Assume no one is doing anything unlawful. Everyone obeys the rules. So
no need to worry about someone sneaking into the station.

I just need some help as I have no idea how to come up with the
passing of the pass to others. How would the pass be validated at the
end? What would be the rules? Any guidance or path would be much
appreciated.

Thank you all in advance.

From the standpoint of requirements (software), my first question would be,
what exactly is the program supposed to do? That is, what are the inputs and
outputs?

As far as the "passing of the pass", I don't see how it matters. Based on
your description, the pass is like a bearer bond. It's the pass that
matters, not the person who has it. The pass is presumably valid for a
specific set of circumstances (bus route(s), times, # of seats) but the
identity of the pass holder is irrelevant.
