project6-testA.tab

Your program should match the following output exactly: (user input in bold text)

Create the following

Objectives 1. Practice using inheritance 2. Practice using polymorphism 3. Practice using an STL container Assignment For this project, you will write a complete C++ program in CodeLite (create a new project using the 2170 template) 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 ca in project6-main.cpp. You can use the following input files for this project project6-testA tab project 6-testB tab
