    Post map pass by refrence?

    Can I pass a map by refrence to a function
    ie:
    Code:
    MainMenu::MainMenu(std::map<string,Book> rlibrary &){
        ptrLibrary=rlibrary;
        while(Menu::get_option()!=6){
            while (!(validate_option(Menu::get_option()))){
                    display_menu();
                    Menu::set_option(Menu::input_option());
            }
            process_option(Menu::get_option());
        }
    }

    Yes, but you've used the wrong syntax. This is correct:
    Code:
    MainMenu::MainMenu(std::map<string,Book> &  rlibrary){
