#include files, preprocessor symbols, and conditional compilation, C++ has features that supersede most of the techniques that required the C preprocessor. Sometimes you need to use the preprocessor to accomplish things you can't with C++, but the need occurs far less often than when using straight C. For example, the Taligent Application Environment uses macros in some places to create meta-information that cannot be found via the current, interim runtime. Be careful though--the Taligent Development System restricts how you can use the preprocessor.
