Academic Personnel Management System in C++

This repository demonstrates an Object-Oriented Personnel Management System in C++ that manages data for both students and teachers. The program is menu-driven and allows persistent storage using file handling.

About the Code

This project showcases fundamental Object-Oriented Programming concepts in C++ by simulating an academic personnel system where users can:

• Add new teacher and student records
• Display all or categorized records
• Identify outstanding teachers and students
• Save and retrieve data using file I/O

The system differentiates behavior using runtime polymorphism and employs dynamic memory allocation to handle objects.

How It Works

1. person is an abstract base class with common attributes (name, cnic) and pure virtual functions for polymorphic behavior.
2. teacher and student inherit from person and implement their own versions of input/output methods.
3. The system uses dynamic polymorphism to operate on person* pointers and determine the object type using typeid.
4. Data is stored to and loaded from a file (personinfo.txt) using standard file streams (ofstream, ifstream).

Class Breakdown

Class Name	Description
person	Abstract base class with common properties like name and CNIC. Defines pure virtual methods for I/O and behavior.
teacher	Inherits from person. Adds fields like number of publications and academic field. Overrides virtual methods.
student	Inherits from person. Adds fields like CGPA and degree. Overrides virtual methods.
main()	Menu-driven interface for creating, displaying, saving, and reading records.

Sample Code

Below is a sample flow of how this program works:

person* p = new teacher();
p->setter();       // Enter name, CNIC, publications, and field
p->getter();       // Display teacher info
if (p->outstanding()) {
    cout << "Outstanding Teacher";
}

ofstream file("personinfo.txt");
p->savetofile(file);   // Save teacher data to file
file.close();
