Mar 4, 2017 · #define simply substitutes a name with its value. May 14, 2011 · What is the point of #define in C++? I've only seen examples where it's used in place of a "magic number" but I don't see the point in just giving that value to a variable instead. Oh Oct 28, 2009 · Is it better to use static const variables than #define preprocessor? Or does it maybe depend on the context? What are advantages/disadvantages for each method? Jul 9, 2018 · The #define version is still a macro. In the normal C or C++ build process the first thing that happens is that the PreProcessor runs, the preprocessor looks though the source files for preprocessor directives like #define or #include and then performs simple operations with them. It has all the expected problems (with macros) including namespace pollution and unexpected parameter behaviour. The compiler never actually sees a macro name at all, what it sees is the replaced text. You'll need to complete a few actions and gain 15 reputation points before being able to upvote.

I've only seen examples where it's used in place of a "magic number" but I don't see the point in just giving that value to a variable instead. Think of it as an automatic search and replace of your source code. The code is expanded at the invocation site. Furthermore, a #define 'd constant may be used in the preprocessor: you can use it with #ifdef to do conditional compilation based on its value, or use the stringizing operator # to get a string with its value. The preprocessor parses the source file and each occurrence of the name is replaced by its associated text. . The #define directive is a preprocessor directive; the preprocessor replaces those macros by their body before the compiler even sees it. ilp mkvmil evgmp9 rhqzso7c kkp 8ow4bp po7i zm2 nwn ai
