C Program to Print All Nodes of Linked List using Recursion

This C Program uses recursive function & displays a linked list. A linked list is an ordered set of data elements, each containing a link to its successor.

Here is the source code of the C program to display a linked list. The C Program is successfully compiled and run on a Linux system. The program output is also shown below.
