Your class will have one member variable of type int to represent the year. This class is a child of the DayOf Year class where the code is given in lecture14 (Lecture14_Code.cpp). Your DateYear class should have the following member functions: a constructor and a default constructor that sets the year to this year, month to 1 and day to 1. an input function that reads the date (day, month, and year). Make sure to check for inaccurate dates. -getter and setters for the year. an output function that outputs the date in form of xx/xx/xxxx. It can display to the screen or the file. A friend function DateCompare that compares two years and returns true if they are the same. A member function BDCountdown, which calculates and returns how many days till your birthday.

Write a program that includes an Employee class that can be used to calculate and print the take-home pay for a commissioned sales employee. All employees receive 7% of the total sales. Federal tax rate is 18%. Retirement contribution is 10%. Social Security tax rate is 6%. Write instance methods to calculate the commission income, federal and social security tax withholding amounts and the amount withheld for retirement. Use appropriate constants, design an object-oriented solution, and write constructors. Include at least one mutator and one accessor method; provide properties for the other instance variables. Create a second class to test your design. Allow the user to enter values for the name of the employee and the sales amount for the week in the second class.Can I please get help writing this in c++ Create a base class called Animal. All animals have a name (i.e. “Fido,” “Thumper,” “Princess,” “Nemo,” etc.) and an age. Provide a default constructor that initializes the age to zero and outputs the message “Invoking the default Animal constructor” and another constructor that allows the name and age to be set by the client. This other constructor should also output the message “Invoking the 2-argument Animal constructor.” Also construct a destructor for this class that outputs the message “Invoking the default Animal destructor.” Your Animal class should have a function called Move that cannot be implemented. That is, it should be declared as a purely virtual function. Your class should also have Get and Set methods to allow the name and age to be accessed. From the Animal class, derive Dog, Rabbit, Fish, and Snake classes. The derived classes should each have constructors and destructors that output an appropriate message (e.g., the…

- Create an overloaded output operator operator<< as a stand-alone function for your DivSales class. You may not use friend .The output operator should display the sales for each quarter of a single division (single object of the class) with labels. Remember DivSales represents the quarterly sales of one division of a company. Use it in your main program to output the quarterly sales for each division in the company (for each object in the divisions array). You will need a loop. After all divisions are displayed, display the total corporate sales for the year.This is my code in c++.
