C Program to Find the Length of the String

This C Program uses recursive function & counts the number of nodes in 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 count the number of nodes in a linked list. The C Program is successfully compiled and run on a Linux system. The program output is also shown below.
