Introduction
The upcoming C23 programming language standard brings exciting new capabilities and improvements for C developers.
Better Integer Handling
One of the most anticipated changes is better support for handling integers through a new integer data type to represent bit-width specific integers. This makes working with integers safer and more flexible.
Enhanced Unicode Support
C23 also improves Unicode support through new syntax for identifiers, allowing developers to use a wider range of characters when naming variables and functions. This enables more expressive and inclusive code.
Strengthened Memory Safety
Security and memory safety get a boost as well. New rules for calloc help avoid buffer overflows and other vulnerabilities related to memory allocation. This allows for more secure C code.
Increased C/C++ Interoperability
For programmers working across C and C++, C23 improves interoperability through new compatibility features. This makes it easier to use both languages within a codebase.

Other New Features
C23 also introduces many other handy new language and library features like new floating point types, integer constants, preprocessor directives, and expanded standard library capabilities.
Conclusion
FAQs
Q: When will C23 be finalized?
A: C23 does not yet have an official release date, but it is expected to be finalized within the next couple of years, likely in 2023 or 2024.
Q: Will I have to update my compiler to use C23 features?
A: Yes, you will need a compiler that supports C23 in order to make use of the new features. Major compiler vendors like GCC and Clang will release upgrades to support C23.
Q: How is C23 different from C11 and C17?
A: C23 introduces many more new features compared to C11 and C17. Those were smaller updates focused mainly on defect fixes and clarifications. C23 is a major update for the language.
Q: Will C23 break backwards compatibility with older C code?
A: The C standards committee is committed to preserving backwards compatibility as much as possible. Some older code may need minimal updates, but C23 should not break a lot of existing code.
Q: Does C23 make C more like C++?
A: C23 does add certain features to make C and C++ more compatible, but C will remain a separate language focused on low-level systems programming compared to C++.
