Course Description
Welcome to Data Structures & Algorithms in C++
This course makes learning to code fun and makes hard concepts easy to understand.
How did I do this? By using animations!
Animating the Data Structures & Algorithms makes everything more visually engaging and allows students to learn more material - in less time - with higher retention (a pretty good combination).
I will use these visuals to guide you, step-by-step, through the entire course.
The course also includes dozens-and-dozens of Coding Exercises. So you can immediately put everything into practice as soon as you learn it (a very important step).
All of this will help you to feel more confident and prepared when you walk into a coding interview.
I have made several Free Sample Videos available for the course so you can see the difference the animations make.
Also, I am very active on the Q&A, so I will be with you every_step_of _the_way.

2 of these exercises I have to watch the video to understand the thinking flow, the rest I coded it myself and I'm quite proud of it all thanks to your explanation, thank you!
By Sahil Kamble on 4/21/2026
I am attending the session from 4 days and i am really getting interest in this its very understable and helpfull for beginner the teaching technique is amazing.
By Rohan Baranwal on 3/3/2026
Great explanation of each and every topic. Scott makes understanding algorithms very easy and you won't forget them at all, descriptive animations of each step will stick in your mind for long time. I'll make sure to visit these videos regularly. Feels like a goldmine
By Naila Taznin Ashrafi on 2/24/2026
Just love the way he picked the complex issues, realistic coding example and the way of explanation. Learning process has been made more relaxing. Huge appreciation!
By ALEX ZENG on 2/2/2026
Halfway review: the most impression for me is that the instructor speak very clearly and no accent. The speed of the speak is so appropriate that I can understand almost all the words even I'm not the native English speaker. However it would be better that more details can be share if the code exercise failed.
By Sai Sharat Karuturi on 1/23/2026
Great course for building strong fundamentals in C++ and Data Structures & Algorithms. Concepts were explained clearly, with good problem-solving practice. It helped improve my coding logic and interview readiness. Highly recommended for beginners and intermediate learners.
By Josiah-David Sykes on 1/16/2026
Intro videos are fairly quick, which makes it seem like it’s better for review of something you have studied previously. If you are generally familiar with the concept, this explains it very well and brings you right back to understanding. If you’re completely new, a new person would probably rewind multiple times and have to search up on the Internet for supplemental info.
By Devon Edward on 1/10/2026
This course has some amazing visuals! It makes it so easy to understand the topics at hand as well as provides you with a starting point in case you are confised on what is it that you need to do.
By Lawrence Righi Boechat on 11/25/2025
It was a fantastic experience. Scott went out of his way to bring visual representations for the algorithm, and I can't compliment him enough on translating the algorithms and data structures to consumable visual objects. This is a fantastic course, I've learned a lot, even being a 5+ year software developer. Just a side note: Some solutions to the final problems like findMaxMin are a little off. But nothing wrong with them, just make sure to dive deep into the problems, that's exactly where you learn!
By Vladyslav Mykhalenko on 11/22/2025
This course provides a good overview of data structures and algorithms. Also, I enjoyed the coding sections, where you can practice and improve your understanding of the course topics. I recommend it to everyone, it's worth its price
