C18 (previously known as C17) is the informal name for ISO/IEC 9899:2018,[1] the most recent standard for the C programming language, published in June 2018. It replaced C11 (standard ISO/IEC 9899:2011).[2]

C18 will be superseded by C2x.[3]

Changes from C11[edit]

C18 addressed defects in C11 without introducing new language features.[2]

The __STDC_VERSION__ macro is increased to the value 201710L.
