Answer to Question #201734 in C++ for Smruti Ranjan Behe

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.

Answer 1

using namespace std;
