Date.h

Create a class to represent a date with the following functionality:

• Create a function to output the date in all of the following 3 formats
• DDD YYYY- 288 2000
• MM/DD/YYYY - 10/14/2000
• Month Day, YYYY – October 14, 2000
• Use a static member variable to keep track of which of the above formats to use when showing the date.
• Supply a static member function to modify the static out-put formatting variable. This function should accept a (string or c-style string) parameter containing an example of the desired out-put format. Be sure to consider what to do if it does not match any of the available formats.
• Create a default constructor that initializes the date’s member variables according to the system date. Using the standard library functions of the <ctime> header.
• Create a constructor allowing date objects to be initialized with dates of the formats shown above. This constructor should accept a (string or c-style string) parameter containing the new date in one of the prescribed formats. Be sure to consider what to do if it does not match any of the available formats
• Create a get member function that will allow the user to enter the date in any of the formats shown above. This function should validate the input.
• Create a function that will show the difference between two dates. You can pick one of the following formats to report this value: days only, days and months, or days, moths and years. Again you are only required to pick one of theses formats. This function should take a CDate as a parameter then report the difference between itself and that date.

Test Program

Write a test program that verifies that each of the requirements above is complete. Your test program must be thorough. Your test program does not have to interact with the user.

Leap Years

 if (year mod 4 != 0)
 {use 28 for days in February}
 
 else if (year mod 400 == 0)
 {use 29 for days in February}
 
 else if (year mod 100 == 0)
 {use 28 for days in February}
 
 else
 {use 29 for days in February}
