Stack with Linked List

A simple C implementation of a stack using a linked list.

Files

• main.c – demonstration program
• Stack.c – stack operations
• header.h – structure and function declarations

Build

Run the following command to compile the project:

gcc main.c Stack.c -o stack_program

Usage

Run the compiled executable:

./stack_program

Block Diagram

Below is a small block diagram showing how the project components interact and how the stack is represented internally (linked list of nodes).

	main[main.c] --> api["Stack API<br/> (push / pop / peek)"]
	api --> stack["Stack (Linked List)"]
	stack --> node1["Node<br/>{data, next}"]
	node1 --> node2["Node<br/>{data, next}"]
	node2 --> null["NULL"]

And a simple ASCII view of the linked list (top is leftmost):

top -> [data | next] -> [data | next] -> NULL
