The older standards -- ANSI X (aka C89), ISO/IEC USD 65 for PDF and USD 82 for hard copy (printed).
The intermediate result type for operands of a given precision are summarized in the adjacent table. Before C99, compilers could round intermediate results inconsistently, especially when using x87 floating-point hardware, leading to compiler-specific behaviour;  such inconsistencies are not permitted in compilers conforming to C99 annex F. IEEE floating point not fully supported. C99 defines a limited number of expression evaluation methods: the current compilation mode can be checked to ensure it meets the assumptions the code was written under. The special values such as NaN and positive or negative infinity can be tested and set. The main function to be evaluated.
Over time, user communities of C language shared ideas of implementing those functions. These ideas eventually incorporated into the definition of the standardized C language in These are now called the C standard libraries.
In s the C language became widely popular, with many universities and organizations begins to create their own variations of the language. At start of s compatibility problems between the various C implementations became apparent.
C89 is compatible in current C compilers, and C code written today mostly based on it. C95 Standard After , C Standards remained static without change for several years. Enhanced multi-byte and wide character supported by the standard library. Addition of digraphs to the language. Specification of standard macros for the operators, e. C90 is stricter in some ways particularly in a declaration that lacks a type specifier no longer hasint implicitly assumed.
There are currently two main versions of the Standard: Many compilers implement a subset of C99's features - sometimes as extensions. Much documentation is available through their website.
Drafts of the Standard are circulated for comment prior to ratification and publication. The drafts, whilst useful, are not definitive: A commonly referenced draft is N a draft of C99 , although many people think that post-C99 drafts are better because there were changes between N and the final standard.
The next version of the Standard not currently being actively worked on is commonly referred to as C0X. The starting point for this version is the N draft, which incorporates the first two technical corrigenda on top of the C99 Standard and N which contains the first three.
Each version of the Standard has a freely available rationale describing the intent of its authors and other helpful background. Each version of the Standard has corrections and updates in the form of amendments and technical corrigenda, detailed on the WG14 homepage.
There is a process for proposing amendments or requesting clarification on the Standard. Neither the Standard nor its amendments are available free of charge, although its drafts, rationales, technical corrigenda TCs and defect report responses are.
One international source is Techstreet. Listed below are direct links to pages for download or free download of the Standard, its TCs, amendments, drafts, rationales and defect report responses for each version of the Standard. The set of documents is comprehensive whereas the list of sources obviously is not.
