Student Management System (C++) 🎓

A console-based Student Management System built in C++, demonstrating practical use of core Data Structures — linked lists, stacks, and queues — alongside modular OOP design.

---

✨ Features

• Add Students — Store Roll Number, Name, Department, Semester, CGPA, and Contact Number
• Display Records — View all enrolled students in a formatted list
• Search — Locate a student instantly by Roll Number (Linear Search)
• Delete Records — Remove a student from the active database
• Undo Delete — Restore the most recently deleted student (Stack-powered)
• Registration Queue — Add pending students to a queue and enrol them sequentially (Queue-powered)
• Sort Students — View the list sorted numerically by Roll Number (Bubble Sort)

---

🧠 Data Structures Used

Structure	Purpose
Singly Linked List	Primary dynamic database — scales without fixed-size limits
Stack (LIFO)	Powers the Undo Delete feature
Queue (FIFO)	Handles the Registration Queue in arrival order
Vector + Bubble Sort	Temporary sorted view without disrupting the main list

💻 Tech Stack

• Language: C++17
• Paradigm: Object-Oriented Programming + Data Structures
• Build: GNU Make / CMake
• Compiler: GCC / G++ (any modern C++ compiler)

🔮 Future Enhancements

• File handling (<fstream>) to persist records across sessions
• Input validation to handle non-numeric entries gracefully
• Binary Search Tree for O(log n) student lookup
• Multi-department filtering and reporting
