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 ...

See the individual topics for more information and examples. Although the compiler does not have a separate preprocessor, the directives described in this section are processed as if there were one. They are used to help in conditional compilation. Unlike C and C++ directives, you cannot use the...
The preprocessor directives instruct the compiler how to treat the source code. For example, under certain conditions, you might want the compiler to ignore portions of the code, and under other conditions, you might want that code compiled. The preprocessor directives give you those options and ...
nothing, in this case the directive has no effect. a line break. Themodule and import directivesare also preprocessing directives. (since C++20) Preprocessing directives must not come from macro expansion. #define EMPTYEMPTY# include <file.h> // not a preprocessing directive ...
Learn about the C++ preprocessor, its directives, and how to use it effectively in your C++ programming.
This document is an official source that describes how the GNU C preprocessor works. The GNU C preprocessor is used by the gcc compiler to preprocess the source files.In the preceding link, you can find how the preprocessor parses the directives and how it creates the parse tree. The ...
C preprocessor directives are copied to the output file without change. You must declare the type and name of each C variable that you intend to use as a host variable in an EXEC SQL BEGIN/END DECLARE section. When invoked in non-PROC mode, ECPG implements the behavio...
Using directives(introduced in lesson2.9 -- Naming collisions and an introduction to namespaces) are not preprocessor directives (and thus are not processed by the preprocessor). So while the termdirectiveusuallymeans apreprocessor directive, this is not always the case. ...
