The next C version is C23, which is the informal name for what will likely become ISO/IEC 9899:2024, the next standard for the C programming language, replacing C17 (standard ISO/IEC 9899:2018). C23 was started in 2016 informally as C2x and is expected to be published in 2024, bringing new features and updates to the C language.

Introduction to C23

Overview of C23

C23 is the next major update to the C programming language, aiming to improve the language’s functionality, performance, and compatibility. The new standard will introduce various features, such as improved support for parallel programming, enhanced security features, and better error handling mechanisms.

Frequently Asked Questions

General Questions

  1. Is C still being updated?: Yes, the C language is still being updated, with the latest standard being C17 and the next standard being C23.
  2. What language is a successor of C?: C++ is a superset and successor to the C language, using an entirely different set of programming concepts.
  3. Is C99 the latest version of C?: No, C99 is not the latest version of C; the latest standard is C17, and the next standard will be C23.

C Standards

  1. Is C11 newer than C99?: Yes, C11 is newer than C99, as it was published in 2011 and replaced C99.
  2. Is C11 better than C99?: C11 addressed some issues in C99 and made some features optional, making it easier for compiler vendors to meet the required function set.
  3. Is C99 still used?: Although C99 is still used in some contexts, its adoption has been limited, and Microsoft has stated that they have no plans to implement the C99 standard.

Compiler and Language Support

  1. Does Visual Studio use C99?: By default, Microsoft’s Visual Studio C Compiler does not follow the C99 standard, but it can be configured to do so.
  2. Does C++ use C99?: C++14 and C++11 are based on C99, while C++17 is based on C11, and C++20 is based on C18.
  3. Is GCC C99 compliant?: GCC is substantially C99 compliant, with some limitations and bugs, especially regarding floating-point issues.

Programming and Development

  1. Is C the mother of all languages?: The C language is considered the mother language of all modern programming languages, as most compilers, JVMs, and kernels are written in C.
  2. Can any language replace C?: While it is possible to replace C with other languages for specific use cases, replacing the systematic use of C with another language is a more complex problem.
  3. Is C worth learning in 2023?: Yes, C is still worth learning, as it remains an essential language for operating systems, compilers, and other system-level software development.

Performance and Comparison

  1. How much faster is C than Java?: C code is generally faster than Java code, with C being approximately 1.69 times faster than Java in some benchmarks.
  2. What is the difference between C and C99?: C is a general-purpose programming language, while C99 is a specific standard of the C language, published in 1999.
  3. What does C do better than Java?: C provides faster processing, as it is a low-level code and a compiled language, whereas Java is a high-level language that requires interpretation.
