Ultimate C++: Basic Modern C++20 to Advanced Multithreading

So, I'm a software developer who has been working in C++ for over two decades now (gods I am old) - but I have to do periodic training for work and somehow HR approved me taking this course for my on going training. I intended to leave it on in the background and just get on with work - but then I started to notice the quality of the instructors lessons and started paying attention because this could be something good to give to our new interns. I will say outright the only reason it is not a full 5 stars is because some of the exercises are worded a bit weirdly that even I had to see the test output to get exactly what the instructor wanted from us - however, the material is very good and gives enough depth to be complete but not so much as to confuse new people (especially with the difficulties listed before each section). If someone worked through this course, practised and studied on their own as well, and did the capstone project they would be more than prepared to seek internships as a C++ developer. The course is well structured, presentation is thorough, and the instructor seems well versed in best practises and general programming. Great work!

# Third Update – Instructor Edited His Response To future students: The instructor replaced his original response (which included personal attacks like "arrogant mediocre employees") and now claims "Udemy controls reviews" and "instructors cannot delete anything." This is false. Both students and instructors can edit on Udemy. His original response is preserved below. Course Summary: 24.5 hours of slide-based theory, minimal live coding Advanced topics (multithreading, concurrency) taught without practical debugging demonstrations "Explore yourself" approach + AI-generated exercises replace instructor-led coding Defensive responses to criticism rather than course improvements Bottom line: Current AI tools (ChatGPT, Claude, etc.) provide better interactive C++ guidance, debugging help, and code examples than this slide-reading course. Full exchange documented below. # My intial review I reviewed the course content and noticed that while it covers advanced topics like async, multithreading, and concurrency, everything is delivered via slides and narration. The instructor seems to rely on AI-generated content, with no live coding, terminal demonstrations, or hands-on walkthroughs—tools like htop are just shown as screenshots. The course’s “coding exercises,” promoted as a key feature, are essentially meaningless—any AI today can generate infinite exercises, teach them, and even solve them. Platforms like LeetCode are already becoming obsolete in comparison, making these exercises feel fake and misleading. Essentially, all this course provides is what one could get by asking an LLM: “Create a syllabus from basics to advanced covering async, multithreading, mutex, STL, and C++20”—slides upon slides, without any real application. For practical subjects like this, slides alone aren’t enough. It’s easy to generate AI content on advanced C++ topics, but teaching them practically is much harder. Without real coding examples and live demonstrations, the material feels theoretical and disconnected from actual programming. ## Instructor first response "You are seeking private tuition to feel good about your skills watching someone else do the work. The course overview clearly mentions that is not the approach we are providing. We take a IDE distraction free code walkthrough approach. Most slides contain code which students can type in the online compiler (introduced early in course) for understanding and diving deeper as needed. The course is handcrafted and coding exercises are kept simple since the coding suite is limited. The capstone project at the beginning of the course explains the limits a willing learner can achieve using the fundamental knowledge of C++ language we are providing through lectures and explanations. We are not selling you how to succeed at you job, that is something the student needs to work on in their circumstances, we provide a solid starting point into the fundamentals of C++ language not a hack to succeed in career by copy pasting from videos and feeling good about self. The exercises are optional if student is confident about their syntax skills. Considering your confidence we request you to submit the capstone project - a distributed key value store using raft or paxos. Also the output of the prompt you mentioned is not what you think. Do things before you talk. Food for thought, AI will be used to replace arrogant mediocre employees and candidates first, don't be one. All the best with your career." " ## My second response I appreciate your reply, though I find the personal attacks ("arrogant mediocre employees") unprofessional and ironic coming from someone whose course delivery model is precisely what AI excels at—reading slides and providing theoretical explanations. On the AI replacement point: Your warning about AI replacing workers is particularly contradictory. The reality is that AI tools can already deliver what your course offers—and do it better. Current LLMs can: Generate comprehensive C++ explanations on demand Provide interactive debugging assistance Walk through toolchain installations (CMake, VCPKG, Ninja, Bazel) Debug compilation errors in real-time Show actual code examples with explanations I've personally used AI to successfully implement complex low-level drivers, debug ESP32 WDT resets at the register level, and configure entire C++ toolchains—tasks requiring deep understanding, not slide-reading. AI enhanced my productivity because I engaged with the actual code and problems. Your "IDE-free, slide-based approach" is exactly what AI has already commoditized. On the capstone challenge: This is deflection. A Raft/Paxos implementation doesn't validate your teaching methodology. If you believe in learning through doing, rewrite your multithreading section with actual coding demonstrations first—show students how to debug race conditions, use thread sanitizers, profile with real tools (not screenshots of htop). The core issue: For system-level C++ programming, especially multithreading and concurrency, students need practical demonstrations. Slides don't show segmentation faults, race conditions, or deadlocks. Your "explore yourself" approach works when students have guidance—which AI now provides better than slide narration. Bottom line: Your course is fundamentally misaligned with how C++ must be taught. The "different approach" excuse doesn't justify the absence of practical demonstration in a discipline where understanding comes from seeing and debugging real code. That's not seeking "private tuition"—that's expecting professional instruction. If you're selling a theoretical overview, market it honestly. Don't package it as practical C++ mastery through "Advanced Multithreading." ------------------------- The complete exchange is documented above. Make an informed decision.

Everything is taught from basics

Audio is easy to understand, pronunciation is clear, helps a lot.
