C Program to Create a Linked List and Display it

This C Program create a linked list & display the elements in the list. Linked list is an ordered set of data elements, each containing a link to its successor. This program is to create a linked list and display all the elements present in the created list.

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

0
 
status of the linked list is
5=>NULL
No. of nodes in the list = 1

Do you want to continue(Type 0 or 1)?
1
Enter the data item
9
Do you want to continue(Type 0 or 1)?

Enter the data item
3
Do you want to continue(Type 0 or 1)?
0
 
status of the linked list is
5=>9=>3=>NULL
No. of nodes in the list = 3
