Singly Linked List
Build a dynamic data structure where each element (node) contains data and a pointer to the next node. Unlike arrays, linked lists can grow and shrink at runtime and provide O(1) insertion at the front, making them ideal for stacks, queues, and situations where frequent insertions are needed.
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 complete LinkedList class with Node structure supporting insertion, deletion, traversal, and search operations.
Learning Objectives
- Understand how nodes connect through pointers to form a chain
- Implement O(1) insertion at the front of a linked list
- Manage dynamic memory with new and delete
- Traverse a linked list using pointer iteration
- Compare linked list trade-offs with arrays
Project Steps
Introduction to Linked Lists
Learn how linked lists store elements using nodes connected by pointers and create the foundation of your LinkedList class.
Adding Elements
Implement methods to add elements at the front and back of the list, track size, and display contents.
Accessing and Removing Elements
Implement methods to access the front element and remove elements from the beginning of the list.
Search and Modification
Implement methods to find elements, insert after a node, remove specific values, and clear the entire list.
