Q1: Write a program that prompts the user to enter information about employees and stores information in a text file. The program should use polymorphism to create the appropriate employee objects. The program should then allow the user to save the employee records to a text file in append mode. Your code should be menu-driven and should prompt for entering employee's records until user decides to quit the program (See Snapshot). Read the saved information from text file and display the employee's records, your program should print out the employee name, ID, type and pay for each employee. The Employee class has following attributes and methods: - Employee name (string) - Employee ID (integer) - getName() function which will return name - getID0 function which will return ID - calculatePay() is a pure virtual function that must be implemented by derived classes. This function has no implementation in the base class, and its purpose is to allow each derived class to define its own version of the calculatePay0 function according to its specific pay calculation. There are three types of employees (derived classes): hourly, salary, and commission. Each employee type has different pay calculation methods: - Hourly employees are paid an hourly rate for the number of hours they work. Their record should also include the hourly rate (double) and the number of hours worked (double). - Salary employees are paid a fixed annual salary. Their record should also include the annual salary (double). - Commission employees are paid a base salary plus a percentage of their sales. Their record should also include the base salary (double) and the total sales (double). The percentage of commission depends on your SAP ID last digit. If your SAP ID last digit is 0 then the percentage of commission should be 0.5 otherwise it should be 0 .[SAP ID Last Digit] for example if SAP ID is 7037238 then the percentage of commission will be 0.8
