This is a great lecture that teaches you how to use C++ like C++. Since he is a working developer, it was also great that he spoke about what was important based on his experience. I felt like I only used C++ with C grammar and STL, and I felt like I used STL without knowing the proper operating principles. I learned a lot about object-oriented concepts and C++ grammar as well as the operating principles of C++ STL. Towards the end, there are many important grammars related to C++11 (lambda, rvalue reference, etc.). I tried to listen for 1 hour a day and finished the course in about 40 days, but while I was learning, I listened to the lectures and tried to recall the lecture contents and make them my own. It seems like a lecture that helped me upgrade myself as a developer. Thank you for making the lecture.
