As much as we try to make it go away, the preprocessor is still here. It is used by many libraries and extensively throughout legacy code. And, in some cases, it is still the best tool to get the job done. In this talk, we will review the C and C++ preprocessor directives, where the abilities of the preprocessor differ between the two languages, and the modern C++ attempts to replace those directives. When this talk is completed, you should be more comfortable both debugging and modernizing preprocessor usage in your code.
