C++ Programming

Hello I need help fixing / finishing my code for this assignment. All i need left is that when a date is set to the last day of the month and incremented, it should become the first day of the following month. For example, when a date is set to December 31 and incremented, it should become January 1 of the following year. AND when a date is set to the first day of the month and decremented, it should become the last day of the previous month. For example when a date is set to January 1 and decremented, it should become December 31 of the previous year. There is an example photo at the bottom.. That's all i need left.. any help is greatly appreciated! Please DO NOT modify date.h or main.cpp.. ONLY dateImp.cpp can be modified!

Prompt:

Develop an implementation file (call it DateImp.cpp) for the modified Date.h. DO NOT MODIFY THE DATE.h OR MAIN.cpp FILES!!! Your solution should have the following overloaded operators:

++ Prefix and postfix increment operators. These operators should increment the objects day member.

-- Prefix and postfix decrement operators. These operators should decrement the objects day member.

- Subtraction operator. If one Date object is subtracted from another, the operator should give the number of days between the two dates. For example, if April 10, 2014 is subtracted from April 18, 2014, the result will be 8.

coutss stream insertion operator. This operator should cause the date to be displayed in the form: April 18. 2014

>> cins stream extraction operator. This operator should prompt the user for a date to be stored in a Date object.

The class should detect the following SPECIAL conditions and handle them accordingly:

When a date is set to the last day of the month and incremented, it should become the first day of the following month.

When a date is set to December 31 and incremented, it should become January 1 of the following year.

When a date is set to the first day of the month and decremented, it should become the last day of the previous month.

When a date is set to January 1 and decremented, it should become December 31 of the previous year.

Input validation: The overloaded >> operator should not accept invalid dates. For example:

The date 13/45/2014 should not be accepted.

Valid year range: 1900

Dont forget to validate the 12 months of the year

Dont forget to validate the days of each month

Restrictions: No global variables, No labels or go-to statements, No infinite loops, No break statements

Here are the given date.h and main.cpp files:
