Day of the Year Modification

Modify the DayOfYear class, written in Programming Challenge 2, to add a constructor that takes two parameters: a string 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.

Add the following overloaded operators:

++ prefix and postfix increment operators. These operators should modify the DayOfYear object so that 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 that 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.

ANSWER IN C++ HERE IS MY CODE FROM THE LAST CHALLENGE

//HEADER FILE
