If you are doing a console app, you could also just save out the data using an fstream. Save it out using a format that you design, and then you can read it back in assuming it is in the same format. It is pretty easy since fstreams have basically the same usage as cin and cout.
I'd suggest making a class if you don't already have one that holds the data. Then just write save and load functions that use an ofstream and an ifstream respectively. If you ever change your format, or add new data, you don't have to change your main code, only the save and load functions.
