is there a way to look at the preprocessor expanded file in C

Question

Hi

i want to know how could we look at the c file after it has been expanded by the preprocessor before compilation with all the macro values put in the code inside the function where ever they are used. in there a way to do it?

Answer 1

You can ask gcc to do it for you gcc -E yourfile.cpp

That will expand macros and include files, all the preproccessing.

Answer 2

Just run it through cpp:

cpp file.c
