Description

GCC C Preprocessor (cpp) is a tool used to transform source code written in the C programming language into another form that is more suitable for further processing. It is a part of the GNU Compiler Collection (GCC) and is used to preprocess the source code before it is passed to the compiler. The preprocessor is responsible for a number of tasks such as macro expansion, conditional compilation, and the inclusion of external files. It also performs tokenization, which is the process of breaking down a file into smaller pieces for easier analysis. The output of the preprocessor is then passed through the compiler, which produces the executable file.
