Automatic Memory Management

• Here is a valid copy constructor for the Department class.

  Department::Department(const Department& b)
  {
     name = b.name;
     if (b.receptionist == NULL)
        receptionist = NULL;
     else
        receptionist = new Employee(b.receptionist->get_name(),
           b.receptionist->get_salary());
  }
  

• The parameter must be const reference because pass by value invokes the copy constructor!
