Question

Practice using inheritance

Practice using polymorphism

Practice using an STL container

Program should be in C++

I have written the .h file code with the help of Chegg, but in my project, its mentioned that I required .cpp file for every .h file. These are the files I required project6-main.cpp Employee.h Employee.cpp Cashier.h Cashier.cpp Manager.h Manager.cpp rubric6.tx. Ignore the files with bold, I am missing .cpp for every header file. While compiling I am getting many errors also, we are not required to mess with project6-main.cpp this file as it is a driver code and given by professor and we are not required to change anything. Can anyone look at my code and fix those error. I have also added input file to check the output. If more information required please let me know. Other details are motioned below.

For this project, you will write a complete C++ program to handle a staff directory and payroll. Extend the driver code located in project6-main.cpp. You need to declare an STL container named employees in the processInputs() function. Additionally, you need to write the Employee, Cashier and Manager classes. Also, you need to use inheritance and polymorphism appropriately. The Employee class needs to store the employee's name. Employees are paid minimum wage ($7.25) for 40 hours each week. The Cashier class needs to store the cashier name and their hourly wage. Cashiers are paid this hourly wage for 40 hours each week. The Manager class needs to store the manager's name, their ID and their weekly salary.
Additionally, add a comment identifying the polymorphic method call in project6-main.cpp.
You can use the following input files for this project:

INPUT (There re two input files)

input file 2:

other input file is large so i am attaching link to access that file (in Link assignment detail is also present)
