How to implement overloaded operator

So here's my question. I have written this chunk of code, and written an overloaded operator for >>

I need to write the information provided by Room.cpp into a file.

How do I implement the overloaded operator to the code? By this I mean, what do I need to change, and how should I change it?

Lost, help! (And thanks, in advance)

If you need to write info into a file you can use the fstream library to stream data to and from any file.
