Create a simple class (DoStuff) containing an int, and overload the operator+ as a member function. Also, provide a print() member function that takes an ostream& as an argument and prints to that ostream&. Add a binary operator- and operator+ to the class as member functions. You should be able to use the objects in complex expressions such as a + b c. Now add the operator++ and operator--, both prefix and postfix versions. Overload the << operator to provide the same functionality as the print() member function. Test the class to show that all requirements work correctly. IN C++
