Preprocessor - CI/CD Glossary Definition
A preprocessor rewrites source before compilation, expanding includes, macros, and conditional blocks.
A preprocessor transforms source code before compilation, handling directives such as #include, #define, and conditional #ifdef blocks in C and C++. Its output is expanded source that the compiler then parses.

In CI
Preprocessor conditionals (#ifdef) let one source tree compile differently per platform or build flag. That flexibility means a change can pass on one CI matrix entry and fail on another, so test every configuration you ship.
