    Vector Trouble - Dev-C++

    I've been working on my text adventure, and in storing all the rooms I've come across a problem. How to store them. I want to keep them all in a vector, so they can be accessed easily, but when I do, I get an error.

    Code:
    #ifndef ROOM_LIST //Prevents repeat definitions.
    #define ROOM_LIST
    
    #include "Room.h"
    #include <vector>
    
    const unsigned short int roomCount=2;
    std::vector<Room> roomList;
    
    Room test1("coc_testhall", "You are standing in a large, open room.  Doors line every wall, with barely a foot between them.");
    roomList.push_back(test1);
    
    Room test2("coc_armorroom", "You are standing in a square room, lined with tables; each holding multiple suits of similar armor.");
    roomList.push_back(test2);
    
    #endif
    The error given is:

    It looks like the code should be in a function.

    What part of it?

    The part designated in the errors are the lines 11 and 14, the ones using the push_back function.

    From what I can tell, I am doing it exactly as shown here.

    No you're not. You're doing it outside of any function. Why do you need those to be global variables?

    Oh! I understand now. Sorry about that laserlight, I completely missed what you were saying...

    I moved it into the main loop and it works perfectly. Thanks, both of you!

    Just for future reference, is there an example/tutorial I could look at that covers why/what I can'/can't use outside functions?

    Thanks!

    You can initialize objects in the global namespace to things that boil down to compile time constants.

    For example if Foo initializes to 0, ok. If Foo does RAII, no.

    Nothing else occurs before main().
