In this assignment will demonstrate your understanding of the following: 1. C++ classes, 2. Implementing a class in C++; 3. Operator overloading with chaining: 4. Preprocessor directives #ifndef, #define, and endir 5. this - the pointer to the current object. In this assignment you will implement the Date class and test its functionality. Consider the following class declaration for the class date: class Date public: Date(); //default constructor sets -et, d-a1, y-2001 Date(unsigned unsigned d, unsigned y); //explicit value constructor to set date equal to today's 1/date.
