Answer to Question #201712 in C++ for Aditya vinayak

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.
