Mini Terminal OS Simulator – CSE 103 Final Project

Mini Terminal OS Simulator is a C programming project built for CSE 103 – Structured Programming Language at East West University. It simulates a mini operating system in the terminal, integrating features like login authentication, file explorer, notepad, student database, and system information display.

📌 Project Information

  • Course: CSE 103 – Structured Programming Language
  • University: East West University, Bangladesh
  • Project Repository: GitHub Link

🎯 Objectives

  • Implement a Login System with username and password validation.
  • Develop a File Explorer for creating, reading, appending, searching, and deleting files.
  • Integrate a Note Pad for simple text editing in the terminal.
  • Build a Student Database to store attendance, marks, and grades.
  • Display System Time and System Information in the console.

⚙️ Features

  • Login & Authentication: Users must log in with correct credentials stored in user.txt.
  • File Explorer: Supports read, append, search, and delete file operations with logs in file_list.txt.
  • Note Pad: Create, open, and edit notes in terminal.
  • Student Database: Add, search, and display student records with automatic grade calculation.
  • System Time: Display live date and clock using time.h.
  • System Info: Display OS and hardware details using systeminfo (Windows).
