Question

Create a "Date" class that contains:

three private data members:

month

day

year

(I leave it to you to decide the type)

"setters" and "getters" for each of the data (6 functions in total)

One advantage of a "setter" is that it can provide error checking. Add assert statements to the setter to enforce reasonable conditions. For example, day might be restricted to between 1 and 31 inclusive.

one default constructor (no arguments)

one constructor with three arguments: month, day, and year

Add assert statements to enforce reasonable conditions.

a printDate function. This function will have no arguments and return void

a sameMonth function. This function will have one Date argument and a boolean return type

In main (in the following order):

instantiate one date object (date1) using the default constructor

use the getters to display the month, day, and year of date1 (should print the default values)

read keyboard input from the user for a month, day and year

use the setters to set the values of date1 to the values that came from the user

read keyboard input from the user for a second date

use the constructor with three arguments to instantiate date2 to the second date input from the user

print both objects using printDate

print a message to say if the two months are the same (testing the sameMonth function)

Your code should be in three files:

Date.h

contains the class definition

Date.cpp

includes "Date.h"

contains the functions for the class

main.cpp

includes "Date.h"

tests the class

Sample Output (Two Runs)

>./main

Testing the default constructor and the getters

The initialized date is (M-D-Y):1-1-1

Please enter a date:(Month Day Year): 11 03 1976

Please enter a second date:(Month Day Year): 03 03 1999

Printing the two days:

The date is (M-D-Y): 11-3-1976

The date is (M-D-Y): 3-3-1999

The months are different

>./main

Testing the default constructor and the getters

The initialized date is (M-D-Y): 1-1-1

Please enter a date:(Month Day Year): 12 15 2009

Please enter a second date:(Month Day Year): 12 25 2020

Printing the two days:

The date is (M-D-Y): 12-15-2009

The date is (M-D-Y): 12-25-2020

The months are the same
