This is a closed-book, closed-notes examination.  There are five
problems.  Do not spend too much time on any problem. Read them 
all through first and solve them in the order that allows you to 
make the most progress.  

For each of the problems, you need to write a function.  You do 
not need to write comments or #include statements.  Assume that
the type bool already exists.  Your program does not have to be 
fancy or user-friendly.  You should make it as simple as possible, 
as long as it does what is required.  


------------------------------------------------------------------------------
Problem 3 (20 points):  

A.  Create a class called date, with data fields for month, day
and year.  They should all be integers.  For month:  1 means 
January, 2 means February, etc.  Look at the other parts of this
question to see what else this class should contain.

B.  Write a member function called get_month to return the month.

C.  Write a member function called get_day to return the day.

D.  Write a member function called get_year to return the year.

D.  Write a nonmember function that takes two dates as parameters
    and returns true if the first date occurs before the second,
    false otherwise.

------------------------------------------------------------------------------
Problem 4 (20 points):  

This problem uses the class from Problem 3, and may use any of the
functions from Problem 3.

A.  Write a class called date_list, containing an array of dates,
and the amount of the array that is filled, as data fields.  Look 
at the other parts of this question to see what else the class 
should contain.

C.  Write a member function called earliest, which returns the
earliest date in the date_list.

D.  Write a member function called count_jan, which returns the
number of dates in the date_list which are in January.
