Modify the DayOfYear class, written in Programming Challenge 2, to add a constructor that takes two parameters: a stringobject representing a month and an integer in the range 0 through 31 representing the day of the month. The constructor should then initialize the integer member of the class to represent the day specified by the month and day of month parameters. The constructor should terminate the program with an appropriate error message if the number entered for a day is outside the range of days for the month given.(Full month names like March, Aprill, May.....)

Add the following overloaded operators:

++ prefix and postfix increment operators. These operators should modify the DayOfYear object so it represents the next day. If the day is already the end of the year, the new value of the object will represent the first day of the year.

-- prefix and postfix decrement operators. These operators should modify the DayOfYear object so it represents the previous day. If the day is already the first day of the year, the new value of the object will represent the last day of the year.

using namespace std;

class DayOfYear

{

public:

int day;

string month;

DayOfYear(int dayentered)

{

day = dayentered;

void print()

{

if (day >= 1 && day <= 31)

{

cout << " Day " << day << " would be " << "January, " << day << endl;

}

if (day >= 60 && day <= 90)

cout << " Day " << day << " would be " << "March, " << day - 59 << endl;

}

if (day >= 91 && day <= 120)

cout << " Day " << day << " would be " << "April, " << day - 90 << endl;

}

if (day >= 121 && day <= 151)

cout << " Day " << day << " would be " << "May, " << day - 120 << endl;
