Can someone help me with this? I added the incomplete c++ code at the bottom of the instructions. Can anyone fix this?
Instructions In this activity, we will extend the functionality of a class called "Date" using inheritance and polymorphism. You will be provided the parent class solution on Canvas, which includes the definition of this class. Currently, the Date class allows users of the class to store a date in month/day/year format. It has three associated integer attributes that are used to store the date as well as multiple defined operations, as described below: setDate-allows the user of the class to set a new date. Note that there is NO date validation in this definition of the method, which is a problem you will solve in this activity. getDate/Month/Year-a trio of getter methods that allow you to retrieve the day/month/and year number from the object. toString - a getter method that generates a string containing the date in "MM/DD/YYYY" format. Your task in this activity is to use inheritance to create a child class of the Date class called "DateExt". A partial definition of this class is provided to you on Canvas to give you a starting point. This child class will achieve the following: 1. Redefine the "setDate" method so that it does proper date validation. This method should return true or false if successful. The date should ONLY be set if the following is valid: a. The month is between 1 and 12. b. The day is valid for the given month. i. ii. I.e., November 31st is NOT valid, as November only has 30 days. Additionally, February must respect leap year rules. February 29th is only valid IF the year given is a leap year. To achieve this, you may need to create additional utility methods (such as a leap year method, for example). You can decide which methods you need. 2. Define additional operations: a. formatSimple-Outputs the date similar to toString, but allows the user to choose the separator character (i.e., instead of "/" they can use "-" to express the date). b. formatWorded-Outputs the date as "spelled out." For example: 3/12/2021 would be "March 12, 2021" if this method is called. i. For this one, you might consider creating a method that uses if statements to return the name equivalent of a month number. Once you are finished, create a test file to test each method. Create multiple objects and assign them different dates. Make sure to pick good dates that will test the logic in your methods to ensure no errors have occurred. Ensure that setDate is properly calling the new definition, as well as test the new operations. Submit your Date Ext definition to Canvas once you are finished. #pragma once #pragma once #include "Date.h" class DateExt :public Date { public: //This calls the parent class's empty constructor. //and then we call the redefined setDate method //in the child constructor. //Note that you do NOT have to modify the constructor //definitions. DateExt(int d, int m, int y) : Date() setDate(d, m, y); { DateExt(): Date() day = -1; month = -1; year = -1; { //Since the parent method "setDate" is virtual, //we can redefine the setDate method here. //and any objects of "DateExt" will choose //this version of the method instead of the parent //method. //This is considered "Run Time Polymorphism", which //is a type of polymorphism that occurs at runtime //rather than compile time(function/operator overloading //is compile time polymorphism). void setDate(int d, int m, int y) { /* Redefine setDate here.../ / Define the rest of the operations below / private: / Define any supporting/utility methods you need here */

The provided C++ code is incomplete and contains errors. It aims to create a child class called "DateExt" that inherits from the parent class "Date" and extends its functionality.

To fix the code, you can make the following modifications:

Remove the duplicate "#pragma once" statement at the beginning of the code.

Ensure the class declaration for "DateExt" inherits from "Date" using the ":" symbol.

Correct the constructor definition for "DateExt" by removing the semicolon after "Date()" and adding a constructor body.

In the "DateExt" constructor body, call the redefined "setDate" method instead of the parent's "setDate" method using the "->" operator.

Add missing curly braces to close the "DateExt" class and the "setDate" method.

Implement the "setDate" method in the "DateExt" class, performing proper date validation based on the given requirements.

Define the additional operations, "formatSimple" and "formatWorded," as mentioned in the instructions.

Add any necessary supporting/utility methods to assist in date validation and other operations.

After making these modifications, you should be able to test the functionality of the "DateExt" class and its methods to ensure proper date validation and formatting. Remember to create a test file to instantiate objects of the "DateExt" class and verify the correctness of the implemented methods.

Note: The specific implementation details and logic for date validation, formatting, and supporting methods will depend on your design choices and requirements.
