Set the month
Set the day
Set the year
Return the month
Return the day
Return the year
Tests whether a year is a leap year
Return the number of days in the month. For example, if the day is 3 – 12 – 2015, the number of days to be returned is 31, because there are 31 days in March.
Return the number of days passed in the year. For example, if the date is 3 – 18 – 2015, the number of days past in the year is 77. Note that the number of days returned also includes the current day.
Return the number of days remaining in year. For example, if the date is 3 – 18 – 2015, the number of days remaining in the year is 288.
Calculate the new date by adding a fixed number of days to the date. For example, if the date is 3 – 18 – 2015 and the days to be added on 25, the new date is 4 – 12 – 2015.
Return a reference to the object containing a copy of the date.
Make a copy of another date. Given a reference to an object containing a date, copy the data members of the object into the corresponding data members of this object.
Write the definitions of the methods to implement the operations defined for the class Date.
