Accessing data function/members?

luke8h (10)
On lines 5, 11, 42 there are issues. I have the incorrect code to tell the program which room i am in. Not sure for the proper code to use to get the correct results. Still very new to C++.

What does your Room class look like? Maybe .description is a member function and not a data member, and you need to call it by using parenthesis ()

What exactly is the problem? Is there a compilation error? Does it not output the correct info at runtime?
luke8h (10)
It does not output the correct info when run.
LB (13399)
Can you give an example?
luke8h (10)
On line 42, 
 
 
 cout << "I am now in a " << rms[i].description<< "." << endl;

This should return with the room I am in, as i go North, south, east or west.
 
 
 cout  rms[i].description

I must have the wrong code, because when the program is run, it returns with
"What shall i do?south
I am now in a.
What shall i do?"

Show the code that sets the descriptions.
