This course covers how to build the most ideal development environment in VSCode, and the process of easily setting up C++ development environment and CMake was particularly helpful. For those who are new to C or C++ language development environments, this course can help reduce trial and error that could range from a few hours to several months. Additionally, the introduction of various useful VSCode extensions was very helpful in improving actual work efficiency. However, it was disappointing that the course presents the 'ideal installation method' as a kind of answer key, making it difficult for students to gain opportunities to explore individual extensions or tools more deeply. While it excels at quickly completing the environment setup, I wish it had provided a bit more room for learners to independently understand and utilize the tools. Furthermore, if the course had covered how to configure settings for directly running or debugging C or C++ code using .vscode/launch.json files, as well as development environment setup methods for Windows OS, it would have been a much more practical and complete course. The fact that these parts were completely missing was somewhat disappointing.
