Code and run your first C++ program about data structures and algorithms in minutes without installing anything!

This course is designed for learners familiar with C++ basics and object-oriented programming. It provides a solid foundation of not just C++, but core data structures and algorithms topics that can be transferred to other languages. The modules in this course cover non-linear data structures like heaps, hash tables (and maps), graphs, and sets. To allow for a truly hands-on, self-paced learning experience, this course is video-free. Assignments contain short explanations with images and runnable code examples with suggested edits to explore code examples further, building a deeper understanding by doing. You'll benefit from instant feedback from a variety of assessment items along the way, gently progressing from quick understanding checks (multiple choice, fill in the blank, and un-scrambling code blocks) to small, approachable coding exercises that take minutes instead of hours.
