The C preprocessor (CPP) is a text file processor that is used with C, C++ and other programming tools. The preprocessor provides for file inclusion (often header files), macro expansion, conditional compilation, and line control. Although named in association with C and used with C, the preprocessor capabilities are not inherently tied to the ...

A C program consists of units called source files (or preprocessing files), which, in addition to source code, includes directives for the C preprocessor.A translation unit is the output of the C preprocessor – a source file after it has been preprocessed.
A variadic macro is a feature of some computer programming languages, especially the C preprocessor, whereby a macro may be declared to accept a varying number of arguments. Variable-argument macros were introduced in 1999 in the ISO/IEC 9899:1999 ( C99 ) revision of the C language standard, and in 2011 in ISO/IEC 14882:2011 ( C++11 ) revision ...
Preprocessing can refer to the following topics in computer science: Preprocessor , a program that processes its input data to produce output that is used as input to another program like a compiler Data pre-processing , used in machine learning and data mining to make input data easier to work with
Syntactic constructs similar to C's preprocessor directives, such as C#'s #if, are also typically called "directives", although in these cases there may not be any real preprocessing phase involved. All preprocessor commands begin with a hash symbol (#) with the exception of the import and module directives in C++ .
The C preprocessor (used with C, C++ and in other contexts) defines an include directive as a line that starts #include and is followed by a file specification. COBOL defines an include directive indicated by copy in order to include a copybook. Generally, for C/C++ the include directive is used to include a header file, but can
The C++ language has an active proposal for transactional memory. It can be enabled in GCC 6 and newer when compiling with -fgnu-tm. [8] [73] Unicode identifiers Although the C++ language requires support for non-ASCII Unicode characters in identifiers, the feature has only been supported since GCC 10.
