Cleaned Assignment Instructions: Implement a class called DayOfYear in C++ that models calendar days, including member functions to access and modify day, month, and year values. The class should include a friend function to compare two DayOfYear objects for equality. Incorporate these features into your code:

• Default constructor initializing the date to January 1, 2009.
• Parameterized constructor taking specific day, month, and year values.
• Output method to display the date in a specific format.
• Getters and setters for individual date components.
• A friend function to compare whether two DayOfYear objects represent the same date.

Additionally, maintain appropriate encapsulation and use proper header guards. Follow best practices for class design, ensuring the friend function is properly declared. Your solution should be complete with the implementation in C++ source files and the header file defining the class and friend function.

Paper For Above instruction

Developing an effective DayOfYear class in C++ requires careful attention to encapsulation, class interface design, and friend function implementation. This paper discusses the key aspects involved in creating such a class, illustrating best practices and providing a robust implementation aimed at accurate modeling of calendar days. The class will encapsulate the attributes representing day, month, and year, and will include the necessary member functions to access and modify these data members, ensuring flexibility and safety in object manipulation.

Begin by defining a class named DayOfYear with three private data members: integers for day, month, and year. To initialize these members, implement a default constructor setting the date to January 1, 2009, which serves as a sensible default. Also provide a parameterized constructor accepting specific values for day, month, and year, allowing creation of specific date objects. These constructors lay the foundation for flexible object instantiation and assist in avoiding uninitialized states.

Next, implement public accessor (getter) functions: get_day(), get_month(), and get_year() for retrieving individual components, facilitating read-only access. Correspondingly, include mutator (setter) functions: set_day(int), set_month(int), and set_year(int) for modifying individual date components, which are critical for dynamic date adjustments in applications. Also, design a setDate() function to set all components simultaneously, improving usability when updating the entire date at once.

The output function, output(), should display the date in a clear format, perhaps as "(day, month year)". This function enables easy visualization of the date object’s state and is essential for debugging and user interaction.

Implement the friend function bool equal(DayOfYear date1, DayOfYear date2) that compares two date objects for equality. Declaring this function as a friend allows it direct access to private members, which simplifies comparison logic. This function should return true if both dates represent the same calendar day; otherwise, false. Proper implementation involves comparing day, month, and year members directly.

The header file, "dayOfYear.h", should include include guards to prevent multiple inclusion issues. It must declare the class, member functions, and the friend function with proper prototypes. The source file, "dayOfYear.cpp", will contain the implementation of all declared functions, maintaining separation of interface and implementation, following C++ best practices.

In conclusion, constructing the DayOfYear class with these specifications results in a robust, encapsulated, and user-friendly design suitable for various applications involving date management. Proper implementation ensures maintainability, ease of use, and extension capabilities, fulfilling the core requirements of modeling calendar days effectively in C++.
