#elselets you create a compound conditional directive, so that, if none of the expressions in the preceding#ifor (optional)#elifdirectives evaluate totrue, the compiler will evaluate all code between#elseand the next#endif.#endif(#endif) must be the next preprocessor directive after#else. ...
Although the compiler doesn't have a separate preprocessor, the directives described in this section are processed as if there were one. You use them to help in conditional compilation. Unlike C and C++ directives, you can't use these directives to create macros. A preprocessor directive must ...

Region and Unregion is new directives. It was not in C and C++ list of directives. I don't know the intention of C# developers to excludes number of directive from C and C++ list but they picked what people use atmost from list of C and C++ directive. Before telling meaning of each ...

When the included file cannot be found in the provided search path, the preprocessor directive#includeis copied into the output file. Preprocessor directives prefixed with a double##are copied verbatim into the output file with a single#prefix. This feature is useful for#ifdirectives that depend...
Programmers will note that this is strange, since most preprocessor directives seem to correspond directly to a unique spp_preprocessor-name.c file. This is easily explained: preprocessor directives correspond to unique preprocessor functions, which usually come one to a file (these directives ...
The original question appeared to ask about suppressing omp target and non-openmp offload directives in the case of compilers which don't support them, but no one gave an answer, other than Kevin's about the facility for optional offload in the compilers which support offload. I think it wou...
The C and C++ programming languages are two of the most commonly used programming languages. Both languages support preprocessor directives, such as source file inclusion (#include), macro definitions (#define), or conditional compilation (#if). ...
