Lightbulb C++ separate code based on the few changes

Hi,

I am working in Visual studio 2008 in which i have written the code in c++,qml,qt.Its a simulator application.

I would like to create a simulator with certain changes. In order to do that i have modified the code with few changes based on the preprocessor condition.

Code:
#define SECOND_SIMULATOR

#ifdef SECOND_SIMULATOR
         code related small changes
else
         code related to main UI
#endif


Is there any way to separate the code other than preprocessor ?

Please wrap all code, files, input & output/errors in CODE tags.
It makes it far easier to read and preserves multiple spaces for indenting or fixed width data.

There are millions of ways to separate the code other than using the preprocessor.

What do you want to use other than whether or not SECOND_SIMULATOR has been #defined to make the decision of what code to use?

There is no possible way to answer that question until you explain what you are trying to do!
