problem is almost solved

Hi all,

I have a simple question. I am working on it for a long time and I feel that I am almost done except for a small problem.
As seen below there is a member function of patient class. It takes variables name and visit_duration. In addition to these variables I want user to be able to enter doctor. This version works but user can not enter doctor.
C++ Syntax (Toggle Plain Text) 
  1. void Patient::input(istream &inpa)
  2. {
  3. 	cout << endl;
  4. 	cout << "Please enter information of patient(name--visit duration--Doctor)" << endl;
  5. 	inpa >> name >> visit_duration;
  6. }
When I define this function as below it gives me the error message " error C2679:"

My all code is shown as below and I attached it also. Can you tell me please how can I include doctor object to input member function?
I appreciate for helps

C++ Syntax (Toggle Plain Text) 
  1. 	inpa >>(name)>> (visit_duration) >> doctor;
your doctor class does not have a >> operator overloaded, hence the compiler places that error.

You can either define the operator, or change the value of doctor through temporary objects and the doctor classes functions.
