ISO C99

ISO C99 is a version of the C programming language standard adopted by the International Organization for Standardization in 1999. It defines the rules and features for writing C programs, ensuring code is consistent and portable across different computers and compilers. C99 introduced new features like inline functions, variable-length arrays, and improved support for complex numbers, making programming more flexible and efficient. It also includes clearer syntax and better handling of different data types, helping developers write reliable and maintainable software. Overall, C99 standardizes best practices to improve the quality and compatibility of C programming.
