I don't know if this is a good book, but it's a little bit confusing for me. These skills are very well-taught. Of course, after reading this book, it is consistent with the previous classic "refactoring-improving existing code design. However, this

Few interpreters (or compilers) Implement switch control. Without it, it's complicated. SharpC divides the switch into two parts: switch (expression) and case. First, let's look at the implementation of Case, which consists of the condition value
