I assume you know how to do basic file i/o?

Write/read how many objects you have, then loop through and load/store those objects.

Tell me how much time did you spent on a search engine to find your answer.
In technical terms, 'saving' is known as serialization[1]
There are plenty of libraries out there to serialize STL containers. You are fortunate enough that Boost's Serialization Library is there on your demand.
Another library is provided on CodeProject
But I would suggest you to use this tool and find the best library for you, yourself.
[1] serialization is actually the process of converting an object into a sequence of bits so that it can be persisted on a storage medium (such as a file, or a memory buffer) or transmitted across a network connection link.
