Queue
Build a FIFO (First In First Out) data structure using a circular array. Queues are fundamental for task scheduling, breadth-first search, and any scenario where processing order must match arrival order.
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 Queue class template using a circular array with O(1) enqueue and dequeue operations, supporting front/back access, size tracking, and real-world use case demonstrations.
Learning Objectives
- Understand the FIFO (First In First Out) principle
- Implement O(1) enqueue and dequeue using circular array
- Manage front and rear pointers for efficient operations
- Handle queue overflow and underflow conditions
- Apply queues to real-world scenarios like task scheduling
Project Steps
Introduction to Queues
Learn the FIFO principle and create the foundation of your Queue class with a circular array.
Enqueue and Dequeue Operations
Implement the core queue operations: enqueue() to add elements, dequeue() to remove elements, front()/back() to peek at elements, and clear() to reset the queue.
Queue Use Cases
Explore real-world queue applications like task scheduling and demonstrate circular array behavior.
