C Program to Reverse a Linked List using Recursion

This C Program uses recursive function & reverses the nodes in a linked list and displays the list. A linked list is an ordered set of data elements, each containing a link to its successor. This program makes each data element to link to its predecessor.

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