Looking at your Contact class I see only this constructor:

Contact(string Addr,string PhoneNum);

This is not the default constructor. The default constructor is the
one that can be called without any arguments. In your case, simply
add this to Contact:

private:
  Contact() {}

You will also want to do the same for your other class(es).
