a$)$ The default constructor should initialise the date to $14$ September $1752.$

b$)$ The overloaded constructor should initialise the date with the given day, month and year.

c$)$ The functions getDay$(),$ getMonth$()$ and getYear$()$ should return the current

day, month and year respectively.

d$)$ The functions setDay$(),$ setMonth$()$ and setYear$()$ should change the current

day, month or year to the given value.

e$)$ The operator $++$ should advance the date by one, and return the new date.

f$)$ The operator $--$ should set the date back by one day, and return the new date.

g$)$ The operator $<$ should calculate whether the receiving date object $($left

argument$)$ precedes the parameter date $($right argument$).$

For example, Date$(1,1,2002)<$ Date$(1,3,2002).$

h$)$ The private member function monthLength$()$ should return the length of the current

month, taking into account leap years. A year is a leap year if it is either $($i$)$ divisible by

$4,$ but not by $100,$ or $($ii$)$ divisible by $400.$ In a leap year, February has $29$ days,

otherwise it has $28$ days.

i$)$ Also overload the insertion operator $<<$ to output a date to the screen. For example,

the date in $($a$)$ above should be written as: $14$ September $1752.$

Test the Date class in a C$++$ program that will do the following:

$$ Declare a new Date object called d$1.$

$$ Display the day, month and year of d$1$ on the screen.

$$ Change the date to $28$ February $2000.$

$$ Advance this date by one and display the new date on the screen.

$$ Now change the date to $1$ January $2002.$

$$ Set this date back by one and display the new date on the screen.

$$ Finally change the date to $31$ December $2002.$

$$ Advance this date by one and display the new date on the screen.

$$ Declare a second date object d$2(1,1,2003).$

$$ Determine if d$1$ is earlier than d$2$ and write the result on the screen.

$$ Operators $++,--$ and $<$ are declared as member functions in the class

declaration above. Implement these operators as friend functions of class

Date also. Run your program twice $($each time with a different version of

the overloaded operator $++,--$ and $<$; comment the other versions out during

each run$).$
