Question

Develop in C++ a class date to represent a calendar. The class should provide the following operations:

A default constructor that initializes a date object to 01-01-1900.

A class constructor that initializes a date object to a correct value using three integer

parameters corresponding to the desired month, day and year.

The function toString() that returns the string version of a date object. For example,

applying toString() to the date 12-01-2000 produces "December 1st, 2000".

The function nextDate() that returns the successive date i.e. the new value of the date object. For example, applying nextDate() to the date 12-31-2000 produces a new date: 01-01-2001. You should take into account if the year is a leap year or not. A leap year is: (1) divisible by 400 or (2) divisible by 4 and not divisible by 100.

The function compareDates() that checks if the date of interest is before, after or equal to the argument date.

A simple run of the driver program follows.

Another run:

***Need a header file and implementation file***
