Linked List Implementation of Stack - Data Structure and Algorithm

This assignment presents a practical implementation of a stack data structure using a linked list in C. The solution includes the necessary code to perform operations such as push (inserting an element), pop (deleting an element), and display (showing the elements in the stack). The code also handles edge cases like an empty stack. The program demonstrates how to use linked lists to manage the stack's elements dynamically. The menu-driven program allows users to interact with the stack by choosing from options like push, pop, display, and exit. The solution demonstrates fundamental data structure concepts and algorithm design principles in a clear and concise manner.

IMPLEMENTATION OF STACK USING LNKED LIST

void push(int value)
{
