What is ISO-IEC 9899:2021?

ISO-IEC 9899:2021, commonly known as C23, is the latest version of the International Standard for the programming language C. This technical article aims to provide a simplified explanation of what ISO-IEC 9899:2021 encompasses and its importance in the world of programming.

The Evolution of C Programming Language

C programming language has a rich history, with its first standardized version released in 1989 as ANSI C or C89. Since then, several revisions and updates have been made to enhance the language's features, address issues, and uphold compatibility. ISO-IEC 9899:2021 represents the most recent significant update to the C programming language standard.

Key Features of ISO-IEC 9899:2021

In the new C23 standard, various new features have been introduced to improve the language's functionality and versatility. Some notable additions include:

Better support for embedded systems and addressing their specific needs.

Enhancements to memory management for more efficient code execution.

Improved type safety and support for atomic operations.

Additional library functions and expanded Unicode support.

Benefits of Adopting ISO-IEC 9899:2021

Implementing ISO-IEC 9899:2021 offers numerous advantages to both programmers and organizations involved in software development:

Improved portability: The standardized nature of ISO-IEC 9899:2021 ensures that C code can be easily migrated across different platforms and continue functioning as intended.
