Stack Program in C using Linked List

Write a code to implement stack program in C using linked list. In this tutorial, You are going to learn how to implement stack data structure using linked  list.

In my previous post, I have explained Stack program in c using array

Stack Data Structure

Let’s revise some of the terminologies of a stack.

i) Stack worked on LIFO (Last In First Out) Principle. It means insertion and deletion are allowed only at one end. The element which added last must be the first element to be removed.

ii) In Stack, Insertion operation is called Push and deletion operation is called Pop . During push operation if memory is not available then it’s termed as StackOverflow. During pop operation if a stack is empty, then it’s called StackUnderflow
