The purpose of this C++ assignment is to show students a simple class that they can practice with.

//DISPLAY 10.3 Class with a Member Function

//Program to demonstrate a very simple example of a class.

//A better version of the class DayOfYear will be given in Display 10.4.

#include

using namespace std;

class DayOfYear

{

public:

    void output( );

    int month;

    int day;

};

int main( )

{

    DayOfYear today, birthday;

    cout << \"Enter today\'s date:\ \";

    cout << \"Enter month as a number: \";

    cin >> today.month;

    cout << \"Enter the day of the month: \";

    cin >> today.day;

    cout << \"Enter your birthday:\ \";

    cout << \"Enter month as a number: \";

    cin >> birthday.month;

    cout << \"Enter the day of the month: \";

    cin >> birthday.day;

    cout << \"Today\'s date is \";

    today.output( );

    cout << \"Your birthday is \";

    birthday.output( );

    if (today.month == birthday.month

        && today.day == birthday.day)

        cout << \"Happy Birthday!\ \";

    else

        cout << \"Happy Unbirthday!\ \";

    return 0;

}

//Uses iostream:

void DayOfYear::output( )

{

    cout << \"month = \" << month

         << \", day = \" << day << endl;

}

Please make following changes and submit program file (.cpp) and output file.

1. Add variable named \'year\' to the class program.

2. Add class function named \'formatted_output\' which will be similar to \'output\'.

3. The function \'formatted_output\' should format date as (MM/DD/YYYY). See image below:

4. Call formatted_output right after function \'output\' is called.

Enter today\'s date Enter month a a number: 08 Enter the day of the month: 10 Enter the year as a number: 2016 Enter your birthday: Enter month a a number 8 Enter the day of the month: 10 Enter year as a number 1978 Today date is month 8, day 10 date is 8/10/2016 Your birthday i month 8, day 10 date is 8/10/1978 Happy Birthday!

if (today.month == birthday.month
&& today.day == birthday.day && today.year == birthday.year)

else
