Delete the node at the given index in linked list in C Programming | Data Structures in C

📋 Description:
In this tutorial, we'll walk through how to delete a node at a specified position from a singly linked list in C. Whether it's the first node, a middle node, or the last node, you'll learn the exact steps to handle each case correctly—updating pointers, freeing memory, and ensuring list integrity.

✅ What you’ll learn:
- Implementing a deleteNode(head, index) function to remove the node at a 0-based index
- Handling edge cases: empty list, deletion of head node, invalid positions
- Real-time pointer traversal to locate the node before deletion
- Reconnecting the list and calling free() to avoid memory leaks

💡 This tutorial is perfect for beginners and intermediate learners who want to strengthen their understanding of linked lists and pointer manipulation in C.

🧠 Prerequisites:
- Basic understanding of C syntax
- Familiarity with pointers and structures
