title: Set data structure reference
body: <p>I was asked to create a game using c++, but before I proceed to implement the game I need to research the set data structure from the c++ standard library (STL). I'm looking for a c++ reference that will show how to use this data structure. Also of use would be some information on what it is typically used for, how it works, and what are the pros and cons of using this data structure as opposed to something else.</p>
