how can do preprocessing for .c source files through command line any pdf would be helpful.
Calling the Compiler from the command line automatically invokes the preprocessor. For example, you can output the preprocessed listing to a specific file with the "-pplist filename" switch, or the -ED switch can be added to the command line to produce a filename.i preprocessed file.
If that is not what you need, can you clarify what you require?
