Introduction

The following paper discusses the development of a simple Employee Information Management System using C++. The system leverages object-oriented programming principles, specifically classes and functions, to model employee data and provide an interactive menu-driven interface for users to view employee details. This project demonstrates fundamental concepts such as class encapsulation, member functions, and user input handling within a console application environment.

Design and Implementation

The core of the application is the Employee class which encapsulates four primary attributes: employee name, address, email, and vacation days. Each attribute is private to enforce data encapsulation, with public getter and setter functions to access and modify these fields. This design aligns with best practices in object-oriented programming, promoting modularity and data integrity.

The class also includes a constructor to initialize employee data with default empty or zero values, ensuring a known state upon object creation. The member functions are straightforward, allowing external code to set or retrieve employee attributes as needed, facilitating ease of data management.

Main Functionality

The application initializes an Employee object with predefined data (name, address, email, vacation days). It then greets the user by name and presents a menu with options to view the employee’s address, email, or vacation days. Users interact with the program through keyboard inputs, selecting options corresponding to their desired actions.

The displayMenu function displays available options dynamically incorporating the employee’s name. The corresponding functions for viewing address (viewAddress) and email (viewEmail) output the employee's details directly to the console, whereas the vacation days are retrieved through the vacationDays function.

The main loop continues until the user inputs 'X' or 'x' to exit. Input validation is incorporated, prompting retries on invalid selections. This implementation illustrates simple control flow mechanisms such as switch-case statements and loops to manage user interactions effectively.

Conclusion

This C++ program provides a fundamental example of object-oriented programming applied to employee data management. It offers a structured approach for creating data models with encapsulation and accessor methods, and a user-friendly interface for data retrieval. The program serves as a foundational template that can be expanded with additional features such as data persistence, multiple employee handling, or graphical user interfaces.
