Beginner C++, pointers and inheritance errors

I am a beginner c++ programmer well versed in csharp however..

For an assignment of mine we have to create a text based maze game, I so far have a header file which contains direction declarations and methods which set directions N,S,W,E

In the main I have gets and sets to set which direction rooms can go in. Below is examples of the code I have included one of each statements to cut the length, i.e only south get and sets.

void Room::setS(Room* nextRoom)
{
south = nextRoom;
}

Room* Room::gS(){return south;}

Room* A = new Room("A");
Room* B = new Room("B");

A->setE(B);
A->setS(E);

Room* myPosistion = A;
string location = *myPosistion->gName();

while(location !="L")
{
    cout << "You are In Room "<< location << endl;
    }

In the while loop I need to be able to access the Room::Methods, (Room::gS()), so something along the lines of 

if(location->gS() == NULL
//do nothing
else 
{
  cout<<"1. South"<<endl;
}

The problem is, I cannot get the location variable to access the Room:: methods, I know im missing something very basic but just cannot get my finger on it..

Thanks for the help

You need to use the pointer to the object instead of the string containing the name

try something more in the lines of :

while(myPosistion->gName().compare("L") != 0 )
{
    cout << "You are In Room "<< myPosistion->gName() << endl;
    if( myPosistion->gS() != NULL )
    {
        cout << "1. South : "<< myPosistion->gS()->gName() << endl;
    }
    //TODO some processing here!
}

when you use the location variable (string), you the reference to the object
