Student Management System

A menu-driven C program to manage student records using structures and file handling. Built as part of the CodeAlpha C Programming Internship (Task 3).

Features

• Add Record – Add a new student's roll number, name, branch, and marks
• Delete Record – Remove a student record by roll number
• Update Record – Modify an existing student's details
• Search Record – Find a student record by roll number
• Display All Records – View all stored student records in a table format

Concepts Used

• Structures (struct)
• File Handling (fopen, fread, fwrite, fseek, fclose)
• Binary file storage for permanent data persistence
• Modular programming (separate functions for each operation)

How It Works

All student records are stored in a binary file (students.dat), so data remains saved even after the program closes. Each operation (add/update/delete/search) reads or modifies this file directly:

• Add – appends a new record to the file
• Search – scans the file for a matching roll number
• Update – locates the record and overwrites it in place using fseek
• Delete – copies all records except the target into a temporary file, then replaces the original
• Display – reads and prints every record in the file

How to Run

gcc main.c -o student_system
./student_system
