In this program, we are going to share how to reverse a linked list using c programming language. 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 reverse a linked list.
Copy the below C program and execute it with the help of C compiler. At the end of this program, We have shared the output of this program.
