Answer to Question #201686 in C++ for XYZ

Question

This program models a database of employees of a company. There are three kinds of employees in the company: manager, scientist and laborers. The database stores a name and an employee identification number of all employees, no matter what their category. However, for manager, it also stores their title and golf club dues. For scientists, it stores the number of articles they have published. Laborers need no additional data beyond their names and numbers. All information to be obtained through a member function getdata(). Information about each employee are to displayed through a constant member function putdata(). Define appropriate classes, member functions. Create an array of objects of each employee type (manager, scientist and laborers separately). Your program should able to read information about each employee type and display the same.
