DayofYearSet is a C++ class to represent a set of DayOfYear objects (in Turkish DayOfYear kümesi). This class has the following functions and features as well as any other functions that you think are necessary (setters, getters, etc.)
• DayofYear is an inner class with all its public and private members.
• DayofYearSet class keeps its elements using a DayofYear * data member.
• Has at least one constructor that takes a vector of DayOfYear objects.
• Overloaded stream insertion operator operator<< will print DayofYearSet details.
• Overloaded operator== and operator!= operators for comparing DayofYearSet objects. Two sets are equal if their elements are equal regardless of the keeping order.
• Member function add adds an element to the set. Please note that no duplicates are allowed in a set.
• Member function remove removes an element from the set.
• Member function size returns the number of elements.
• Overloaded binary operator+ returns the union set.
• Overloaded binary operator- returns the difference set.
• Overloaded binary operator^ returns the intersection set.
• Overloaded unary operator! returns the complement set. Note that there are only 365 days in a year.
• Overloaded binary operator[] returns the element at given position. • Uses keywords decltype and auto in its implementation.
• The class will have a static function that returns the total number of DayOfYear objects alive in all the sets. Be careful here because there could be more than one set alive at the same time.

Your class uses a namespace and separates the class interface from the implementation.

Your driver code will be in a separate file. It will do the following
• Test each function at least 2 times and printing the results. Do not forget to test the constructors.
• Send the class objects to functions using call by value and call by reference and testing the results.
• Test the De Morgan rule for sets with at least 5 different set pairs. Note that for sets s1 and s2, De Morgan says that !(s1 + s2) == !s1 ^ !s2
• Writes some sets to text files. Do not forget to include your saved files.

Notes:
• Do not use any functions from the standard C library (like printf) • Do not use anything that we did not learn in the lectures.
• Check the validity of the user input.
• You should submit your work to the Teams page.
• Hint: Linux utility valgrind can test for memory leaks and other heap errors.
