📌 Summary:
《Modern C》書籍推出了適應 C23 標準的新版本，現已在線免費提供。這個新版本全面更新了內容，涵蓋 C23 標準引入的重要新功能，包括位元精確型別(_BitInt(N))、新的標頭檔如 <stdckdint.h> 和 <stdbit.h>、對於現代架構的 128 位元類型支援、枚舉類型改進等。此外還新增了 nullptr 常數、屬性註解、auto 和 typeof 的型別推斷、預設初始化等功能，並增添了複合表達式、Lambda、國際化及程式故障處理等內容。

🎯 Key Points:
- 新版本已於 2024 年 10 月 15 日更新，同步配合 ISO 發布 C23 標準的時程
- 主要新增功能包括：位元精確型別、溢位檢查工具、位元操作函式庫、擴展至 128 位元的型別支援
- 新增語法特性：nullptr 常數、屬性註解、auto 和 typeof 型別推斷、預設初始化功能等
- 書籍附錄提供過渡工具，協助開發者在現有平臺上立即開始使用 C23 功能

I’m sure @JensGustedt has a hidden philosoper in him somewhere. This description is pithy and genius:

“There are two categories of aspects to consider in a C program:

syntactical aspects
(how do we specify the program so the compiler understands it?)

and

semantic aspects
(what do we specify so the program does what we want it to do?).

In the following subsections, we will introduce the syntactical aspects (grammar) and three different semantic aspects: declarative parts (what things are), definitions of objects (where things are), and statements (what things are supposed to do).”

I think that’s C (and most basic programming) in a nutshell.

@srj Since this seems difficult to find, I now added a direct download link to the code examples on https://gustedt.gitlabpages.inria.fr/modern-c/

C2Y will have complex literals!

@rcs @nostarch they seem to be more efficient than mine ... #ModernC the C23 edition seems still have some weeks to go

In the phrase "The comma is an ambiguous fellow in C." my copy-editor changed "fellow" into "character". I am not sure that they noted the double sense of that phrase, but I actually like it. (My French environment with its fable for ambiguities probably shows.)
