program will allow the user to keep track of airline reservations

[Paul_23]

I have been working on this for a few days now and I am having trouble understand how to create a paralell array between the seatList and seatPrices so the user can reserve that seat. I was wondering is someone could explain how it would work so I can write the code?

Thanks

I think you should use multi-dimentional array which can resolve your problem.

This is where classes or structs come into play.

Unfortunately, I haven't learned classes or structures yet. But the multi dimensinal array helped. Thanks everyone
