In this program, we are going to share a c program to search for an element in the linked list without using recursion.
If you are a beginner and want to start learning the C programming, then keep your close attention in this tutorial as I am going to share a C program to search for an element in the linked list without using recursion with the output.
We have designed this program for beginners for learning purpose. Copy below C program and execute it with c compiler to see the output of the program.

Enter the number of nodes: 10
