Macro expansion in c. Visual Studio can now expand C and C++ macros. Depending on which compiler you use, there should be a way to see the code after the preprocessor (which does the macro expansion, macros are not known by the compiler at all) is done.

An X macro application consists of two parts: The definition of the list's elements. Dec 9, 2011 · Macro expansion is always just a textual transform of the input source code.
