Answer to Question #276011 in C++ for Asim

Question

Derive a class called employee2 from the employee class in the EMPLOY program in this

chapter. This new class should add a type double data item called compensation, and

also an enum type called period to indicate whether the employee is paid hourly, weekly,

or monthly. For simplicity you can change the manager, scientist, and laborer classes

so they are derived from employee2 instead of employee. However, note that in many

circumstances it might be more in the spirit of OOP to create a separate base class called

compensation and three new classes manager2, scientist2, and laborer2, and use

multiple inheritance to derive these three classes from the original manager, scientist,

and laborer classes and from compensation. This way none of the original classes

needs to be modified.

Answer 1

#include <iostream>
#include <string>

class employee
{
    std::string employee_name;
};
class employee2 : public employee
{
    std::string role;
};
class compensation
{
    double compensation;
    enum Period {hourly, weekly, monthly};
};
class manager : public employee2, public compensation
{
    
};
class laborer : public employee2, public compensation
{
    
};
class scientist : public employee2, public compensation
{
    
};
