};
class Course
{
  int ID;
  protected:
  Char Title[30];
  public:
  Course();
  void Initiate();
  void Display();
};
class Schedule: public Course, private Teacher
{
  int DD,MM,YYYY;
  public:
  Schedule();
  void Start();
  void View();
};
void main()
{
  Schedule S;
}

(i) Which type of Inheritance out of the following is illustrated in the above example?
Single Level Inheritance, Multilevel Inheritance, Multiple Inheritance
(ii) Write the names of all the members, which are directly accessible by the member
function View() of class Schedule.
(iii) Write the names of all the members, which are directly accessible by the object S
of class Schedule declared in the main() function.
(iv) What will be the order of execution of the constructors, when the object S of class
Schedule is declared inside main() function?

What is the difference between public member and private member of a class.

Differentiate between protected and private members of a class in context of Object Oriented Programming. Also give a suitable example illustrating accessibility/non-accessibility of each using a class and an object in C++.
