Question

C++  Polymorphism

Please read the instruction!!

In this exercise, you are given an abstract base class and you are asked to provide concrete (non-abstract) derived classes. Then write the test code to test those classes. The test code scans the data entered on the keyboard using the following format.

For the information of a part-time employee, the line starts with the letter P followed by other information separated by commas.

P,empname,hourly rate,hours worked

For the information of a full-time employee, the line starts with the letter U followed by other information separated by commas.

U,empname,salary

You are required to write the function getEmployeeInfo that scans the data from keyboard and creates an object of the appropriate type and return a unique_ptr that 'points' to the object.

In the main function, you can call the getEmployeeInfo function and then call a member function to print the employee info.

For keyboard input,

P,Ivy Oaks,21,20

The output must be

Employee Name: Ivy Oaks
Pay Amount: 420
