First, it would help if you said what environment
you're on: Windows, Linux, or something else.

I have read that the C/C++ preprocessor should
only be used for its intended application.  One
alternative is GNU m4:

Or you could write some scripting, if the task is
simple, calling perhaps 'cat' and the 'bash'
redirection operator '>'.
