This lecture is worth more than the price of the lecture. Starting from the computer structure, you can understand the memory structure well, and based on that, the instructor explains the necessary parts of C++ grammar with examples that are easy to understand. The instructor condenses the know-how of the instructor and explains it in a short period of time, including WINAPI, client structure, server structure, and client-server connection, which are easy to get lost in when studying alone. I highly recommend it to beginners. I strongly recommend it to students who want to enter the game industry.
