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 ...

preprocessor directives and regular statements in c/c++ serve different purposes. directives are used to direct the preprocessor to how to handle your source code before compilation, while regular statements are part of the actual program's logic and execution. additionally, directives are processed ...
directives: #define #undef #include #if #else #elif #endif #ifdef #ifndef #error (#warning is NOT A STANDARD DIRECTIVE, since not shown in the page above, but most compilers have it. more:http://stackoverflow.com/questions/171435/portability-of-warning-preprocessor-directive) ...
The multi-line macro can contain preprocessor directives. Conditional directives are very useful in this context. Note however that preprocessor definitions (with#define,#defmacro, or#undef) nested inside multiline macros are only valid within the macro. ...
This dwm 6.5 (061e9fe, 2024-03-19) side project has a different take on dwm patching. It uses preprocessor directives to decide whether or not to include a patch during build time. Essentially this means that this build, for better or worse, contains both the patchedandthe original code....

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 ...
