C++ that you can learn by following I tried to code again based on old memories with a hardened mind, but the old code (around 1996) and the current code are very different. At that time, I remember developing IBM API Programming and a business document editor in C in a DOS environment and converting the program to C++ in a Windows environment. My recent work is very far from coding, but I decided to code again to conceptually implement the main technology of the development project. With the thought that creation comes from imitation... I looked at the SDK reference code, but there were many differences from my old memories, and sentences that I saw for the first time. The thought crossed my mind that I had jumped in too recklessly. "Ah! I have to learn again..." I borrowed a C++ book from the library and looked at it. Well, if one book doesn't work, I'll look at two, and if two books don't work, I'll look at three... "Reading a lot of books doesn't mean you can do it..." While searching for information related to 3D printers, I found information on the C++ course on the Lisophia homepage. I was watching a lecture on YouTube and heard that a lecture was opened on Inflearn, so I registered right away. I registered during the free registration period and am continuing to take the lecture, but I still feel uneasy. I feel like I owe something to listen to such a great lecture for free. You can check the recorded time of the lecture on the screen, and considering that you recorded the lecture until late at night and even considered editing, it is a lecture that shows a lot of effort and sincerity. Despite your sore throat, you give passionate lectures, lectures that point out the key points, and share real-life cases and the professor's experience, so it would be best for you as a lecturer to follow along diligently. I registered for the lecture after hearing the news of the opening of the game package lecture. I should listen to it after finishing Mr. Tta-bae's lecture. I fell asleep in front of the monitor with my headphones on (sorry...), and then went back and forth to the end. I will listen to it two more times. There is a saying that writings carved in stone last a thousand years. I think it would be better if I listened to it with my son. Thank you, professor, for creating a great course. Happy New Year
