I really could use help on my last C++ project on Inheritance and Polymorphism!

-

Objective: The main goal of this last project is to implement a simple inheritance hierarchy between the Person and Employee class.

-

Description: Declare and implement the Employee class as a derived class of the Person class, which is already implemented in the demo codes pasted at the bottom of this post. Note that your project doesn't need to include the Student class. Please also feel free to modify the Person class. For instance, you can replace the data type for birthday to string.

-

Specifically, your project will include Person as the base class, and Employee as the derived class of Person. Your Employee class will include the following data members:

1. year of employment (e.g., 2012)

2. base salary

3. a dynamic array to keep track of the annual salary increase rate since the year of employment. For instance, an employee joined the company in year 2013, his salary increase rates in 2014, 2015, and 2016 were 10%, 7%, and 11%, respectively. This dynamic array will then hold the following three numbers: 0.1, 0.07, and 0.11. Furthermore, let bSal be the base salary, the current salary of the above employee should be equal to: bSal*1.10*1.07*1.11. Note that although the size of this array is derivable from the year of employment, you are recommended to include two additional data members to manage the capacity and size of this array.

-

At the minimum, your Employee class needs to include the following function members:

- a default constructor

- the Big-3: destructor, copy constructor and overloaded assignment operator

- an accessor to return the current salary of an employee

- an accessor and mutator for each of the above data members. It's sufficient to return the salary increase rate in a specific year.

- an overloaded put operator (

- override the output() function in the base class, as this function is virtual in Person.

-

Please provide a simple character-based interface to allow the user to test each of the above member functions. Make sure you test the output() function using Person pointers and observe polymorphism in action.

-

Submission requirements: Please use separate compilation and submit your source code into one zip file. Your project will include two header files (one for the Person class, the other for the Employee class) and three .cpp files. Because this is Chegg, you only need to copy and paste your code for the five files in your post. Thank you!
