C++ Project Modify the Date Class:

Standards

Your program must start with comments giving your name and the name of the assignment.

Your program must use good variable names.

All input must have a good prompt so that the user knows what to enter.

All output must clearly describe what is output.

Using the date class, make the following modifications:

Make the thanksgiving function you wrote for project 1 into a method of the Date class. It receive the current year and returns the date for Thanksgiving.

In the Date class there are only a few overloaded operators for comparison. Add all of the following: <=, >=, and !=

Add a method to return the season as an integer: 0=winter, 1=spring, 2=summer and 3=fall for the northern hemisphere.

Your main program should illustrate the use of each method.

You may use March 20th for the first day of Spring. Use June 20th for the first day of summer, September 22 for the first day of fall, and December 21 as the first day of winter. You will find the overloaded operators handy for this. A nice solution for this is to use an array to store the first date for each season, then loop to see where a date falls.

Main.cpp:

#include "Date.h"

#include

using namespace std;

// Start of main

void bubbleSort(Date date[], int n)//is an array of dates and is the size of the array

{

int i, j;

for (i = 0; i < n - 1; i++)

// Last i elements are already in place

for (j = 0; j < n - i - 1; j++)

if (date[j] > date[j + 1])

{

Date temp = date[j];

date[j] = date[j + 1];

date[j + 1] = temp;

}

}

int main() {

// Declare arrays and variables
