📘 Course Registration System – C++ Console Program

This program demonstrates a simple course registration system using multi-linked lists in C++. It helped us understand how data can be linked and accessed using multiple pointers across different structures like courses and enrolled students.

The project focuses purely on Data Structures (specifically multi-linked lists) and function-based modular programming without file handling or OOP.

💡 Core Concepts Used

• Multi-Linked Lists:
  Each course maintains a separate linked list of students enrolled in it.

• Dynamic Memory Management:
  Nodes (courses/students) are created and deleted during runtime using pointers.

• Function-based Structure:
  Code is divided into reusable modular functions for each task.
