A question regarding preprocessor

[LarryChen]

I wonder if there is any command line option under VS to save the output of preprocessor? Thanks.

It's useless, the compiler already reads that

[LarryChen]

Sometimes it is very useful. For example, if I define a lot of macro, I want to check how they are processed to make sure there isn't any problem. After the compiler reads them, there is no chance for me to keep track of them.

Yes, it's in the project properties somewhere.

For MSVC that is C/C++, Preprocessor, Generate Preprocessed File
Edit: Oh, the command line option is /P

To view all options type cl -? in a command shell.
