    Vector within a vector

    Is it possible to have vectors made up of vectors?

    If so, how would I accomplish this? If not, is there an alternative that would provide the same result?

    I'm confused of how to do a vector within a vector....because I originally thought of:

    Code:
    vector<vector<string>> vstrInventory;
    For example, but that didn't seem right to me for some reason :/

    You have to use some spaces.
    Code:
    vector< vector<string> > vstrInventory;
    I'm not sure why.

    The token >> makes the compiler confused when you use it with nested templates, so you must use a space between the any two > signs:

    std::vector<std::vector<std::string> > vec2D;
