C code of full linked list all the methods(insert, delete, search, display,exit)

In this c code I've tried to complete the all of the task of linked list.Here, four methods of linked list has been used :

1. insert method at line no : 9
2. search method at line no : 24
3. delete method at line no : 40
4. print method at line no : 64

And start my main method at line no : 75

Suggestion:


Don't try to direct copy paste please. This habit will damage your coding power. 
Coding is an energy, is a habit, is a funny....
So, try to solve your coding problem by yourself.
For more on linked list, you can see my previous  large lecture on linked list.
