But basically I want to write an array of complex objects to a file to store them and then be able to load the saved data into the arrays again once the program is ran again after exit.
Somebody suggested just storing the data in a text file using XML, and then parsing the text file using the tags stored in the text file.
I was just wondering what the most efficient and best way would be to store the data.
As for a bit of background on the project, the project is an airport booking system which consists of 2 airplanes which hold 24 passengers. The planes can have multiple flights and upto 24 passengers. So passengers must be assigned to flight seats on the planes. All of this data is stored in two objects, one called passengers which has an array size of 24 (currently, I wish to turn this into a vector, but I have not used vectors yet) and flights with an array size of 100 (which I also wish to turn into a vector).
I hope this is enough information for you guys to get an idea. I just want to know the best way to go about it, so that I know from the start, rather than finding out down the line and realising that my way is deprecated or incredibly inefficient.

Also, unrelated, but if possible, if anyone has experience with vectors I'd love to know how to use them, as they seem awfully complex when I last looked at them anyway, and I'm not really sure how they work.
Thanks as always guys, Conner.
