Stack
Build a Stack data structure that demonstrates the LIFO (Last In First Out) principle. Stacks are fundamental in computer science, powering function calls, undo systems, and expression evaluation. You'll implement a template-based stack using a dynamic array internally.
Data Structures & Algorithms Project
The difficulty level shown is relative to other DSA projects. This project assumes you're comfortable with C++ fundamentals including classes, pointers, and memory management. If you're new to C++, we recommend completing our core C++ lessons first.

What You'll Build
A Stack class template with push, pop, top, and utility operations that handles dynamic resizing and demonstrates the LIFO principle used in function call stacks and undo systems.
Learning Objectives
- Understand the LIFO (Last In First Out) principle
- Implement O(1) push and pop operations
- Handle stack underflow with exceptions
- Use dynamic arrays for automatic resizing
- Apply stacks to real-world problems like balanced parentheses
Project Steps
Introduction to Stacks
Learn the LIFO principle and create the foundation of your Stack class with dynamic storage.
Push, Pop, and Top Operations
Implement the core stack operations: push() to add elements, pop() to remove them, and top() to view the top element.
Clear, Swap, and Practical Applications
Add utility operations and demonstrate a classic stack application: checking balanced parentheses.
