ISO C++ keywords The C++98 standard recognized the following keywords: and and_eq asm auto bitand bitor bool break case catch char class compl const const_cast continue default delete do double dynamic_cast else enum explicit export extern false float for friend goto if inline int long mutable namespace new not not_eq operator or or_eq private protected public register reinterpret_cast return short signed sizeof static static_cast struct switch template this throw true try typedef typeid typename union unsigned using virtual void volatile wchar_t while xor xor_eq Specific compilers may (in a non-standard compliant mode) also treat some other words as keywords, including cdecl, far, fortran, huge, interrupt, near, pascal, typeof. Old compilers may recognize the overload keyword, an anachronism that has been removed from the language. The current revision of C++, known as C++11, added some keywords: alignas alignof char16_t char32_t constexpr decltype noexcept nullptr static_assert thread_local C++11 also added two special words which act like keywords in some contexts, but can be used as ordinary identifiers most of the time: final override It would be bad practice to use these as identifiers when writing new code. The C++98 keywords auto, default, delete and using have additional or changed uses in C++11. Some old C++98 compilers may not recognize some or all of the following keywords: and and_eq bitand bitor bool catch compl const_cast dynamic_cast explicit export false mutable namespace not not_eq or or_eq reinterpret_cast static_cast template throw true try typeid typename using wchar_t xor xor_eq C++ reserved identifiers Some "nonstandard" identifiers are reserved for distinct uses, to avoid conflicts on the naming of identifiers by vendors, library creators and users in general. Reserved identifiers include keywords with two consecutive underscores (__), all that start with an underscore followed by an uppercase letter and some other categories of reserved identifiers carried over from the C library specification. A list of C reserved identifiers can be found at the Internet Wayback Machine archived page: http://web.archive.org/web/20040209031039/http://oakroadsystems.com/tech/c-predef.htm#ReservedIdentifiers It would be nice to list those C reserved identifiers, for the moment All Standard C Library Functions have already been listed C++ Programming C++ Programming: Language Keywords
