C – Preprocessors – Tutorialspoint

tutorialspoint.com2020. 10. 18. · The C Preprocessor is not a part of the compiler, but is a separate step in the compilation process. In simple terms, a C Preprocessor is just a text substitution tool and it instructs the compiler to do required pre-processing before the actual compilation. We’ll refer to the C Preprocessor as CPP. All preprocessor commands begin with a hash symbol (#).

Preprocessor directives – C++ Tutorials

cplusplus.com2014. 11. 11. · Because preprocessor replacements happen before any C++ syntax check, macro definitions can be a tricky feature, but be careful: code that relies heavily on complicated macros may seem obscure to other programmers, since the syntax they expect is on many occasions different from the regular expressions programmers expect in C++.

Preprocessor – Wikipedia

en.wikipedia.org2020. 11. 1. · In computer science, a preprocessor is a program that processes its input data to produce output that is used as input to another program. The output is said to be a preprocessed form of the input data, which is often used by some subsequent programs like compilers.The amount and kind of processing done depends on the nature of the preprocessor; some preprocessors are only capable …

Concatenation (The C Preprocessor)

gcc.gnu.org2020. 10. 15. · Keep in mind that the C preprocessor converts comments to whitespace before macros are even considered. Therefore, you cannot create a comment by concatenating ‘/’ and ‘*’. You can put as much whitespace between ‘##’ and its operands as you like, including comments, and you can put comments in arguments that will be concatenated.
