C++ 从结构实例调用变量语法问题C++；

虽然我不喜欢问一个我不知道的简单语法问题，但作业截止日期迫在眉睫，我完全被难住了，我查到的信息似乎都没有用处。我在头文件中有一个结构：

struct roomStruct
{
    // The room the player is currently in, and its interactive objects.
    string roomName;
    string size;
    int exits[dirnum];
    bool rustyKeyIn;
    bool goldKeyIn;
    bool copperKeyIn;
    bool rustyDoorIn;
    bool goldDoorIn;
    bool copperDoorIn;
    bool torchIn;
    bool toyIn;
    bool leverIn;
    bool brokenDoorIn;
    bool oldCheeseIn;
    bool toyBoxIn;
    bool skeletonIn;
    bool ghostIn;
};

和一个这样的结构实例（每个gen_rooms编号有更多，格式相同）：

然后，我尝试从上面的实例中调用roomName变量，但我不知道如何实现。我知道这是一个丑陋的文本冒险输入法，但这不是当前的问题

int main()
{
    string verb;
    string noun;

    roomStruct rooms[roomnum];
    genRooms(rooms);

    int currentRoom = entrance;

    cout << "Welcome to GHOST HOUSE!!!" << endl << endl << "Please enter commands in the format 'verb -> enter -> noun -> enter' in all lower case." << endl << endl;

    // All commands will be in the format 'verb, noun', with the noun not being required for all commands. Currently, lower case is required.
    cout << "You are in the " << roomStruct.roomName << "." << endl;
    cout << "What do you want to do?" << endl;
    cin >> verb >> noun;

intmain（）
{
字符串动词；
字符串名词；
roomStruct房间[roomnum]；
房间；
室内=入口；
不能这样做：

int main(){
string verb;
string noun;
roomStruct rooms[roomnum];
genRooms(rooms);
int currentRoom = entrance;
cout << "Welcome to GHOST HOUSE!!!" << endl << endl << "Please enter commands in the format 'verb -> enter -> noun -> enter' in all lower case." << endl << endl;
// All commands will be in the format 'verb, noun', with the noun not being required for all commands. Currently, lower case is required.
cout << "You are in the " << rooms[currentRoom].roomName << "." << endl;
cout << "What do you want to do?" << endl;
cin >> verb >> noun;

intmain（）{
字符串动词；
字符串名词；
roomStruct房间[roomnum]；
房间；
室内=入口；
cout@Triiby>>您是否将“rms”存储在任何地方？如果没有，那么您如何从主功能访问它？不太清楚您的意思，但实例（带有rms的实例）位于.cpp文件中，而不是标头中，如果这有帮助的话。它确实存在，谢谢：）毕竟可能能够及时编写此内容！
int main(){
string verb;
string noun;
roomStruct rooms[roomnum];
genRooms(rooms);
int currentRoom = entrance;
cout << "Welcome to GHOST HOUSE!!!" << endl << endl << "Please enter commands in the format 'verb -> enter -> noun -> enter' in all lower case." << endl << endl;
// All commands will be in the format 'verb, noun', with the noun not being required for all commands. Currently, lower case is required.
cout << "You are in the " << rooms[currentRoom].roomName << "." << endl;
cout << "What do you want to do?" << endl;
cin >> verb >> noun;
