This class is missing a number of functions. Rewrite the class declaration to follow best practices, e.g., operators, three important functions, and printing. The functions you write must be const-correct. You do not need to create, an iterator, begin function, or end function. class AppointmentSequence private: std::string title 11/ short description k * * One Appointment Node - Linked List Building Block struct Node{ Appointment data; ///
