2. Day of the Year
Assuming that a year has 365 days, write a class named DayOfYear that takes an integer
representing a day of the year and translates it to a string consisting of the month followed
by day of the month. For example,
Day 2 would be January 2
Day 32 would be February 1
Day 365 would be December 31.
The constructor for the class should take as parameter an integer representing the day of
the year, and the class should have a member function print() that prints the day in the
month-day format. The class should have an integer member variable to represent the day
and should have static member variables of type string to assist in the translation from
the integer format to the month–day format.
Test your class by inputting various integers representing days and printing out their
representation in the month–day format.3. Day of the Year Modiﬁcation
Modify the DayOfYear class, written in an earlier Programming Challenge, 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.
