The C23 edition of Modern C

The C23 edition of Modern C is now available for free download from

https://hal.inria.fr/hal-02383654

This new edition has been the occasion to overhaul the presentation
in many places, but its main purpose is the update to the new C
standard, C23. The goal was to publish this new edition of Modern C
at the same time as the new C standard goes through the procedure of
ISO publication. The closest approximation of the contents of the new
standard in a publically available document can be found here. New
releases of major compilers already implement most of the new
features that it brings.

Among the most noticeable changes and additions that we handle are
those for integers: there are new bit-precise types coined _BitInt
(N), new C library headers (for arithmetic with overflow check) and
(for bit manipulation), possibilities for 128 bit types on modern
architectures, and substantial improvements for enumeration types.
Other new concepts in C23 include a nullptr constant and its
underlying type, syntactic annotation with attributes, more tools for
type generic programming such as type inference with auto and typeof,
default initialization with {}, even for variable length arrays, and
constexpr for named constants of any type. Furthermore, new material
has been added, discussing compound expressions and lambdas,
so-called "internationalization", a comprehensive approach for
program failure.

Also added has been an appendix and a temporary include header for an
easy transition to C23 on existing platforms, that will allow you to
start off with C23 right away.

Manning's early access program (MEAP) for the new edition is still
open at

Unfortunately they were not yet able to tell me when their version of
the C23 edition will finally be published.
