"Common sense" with regard to preprocessing Preprocessing is not a compilation, nor is it "precompiled." Preprocessing is not available in every language. The pre-and C + + preprocessing simply divides the source program into segments (phase) and does not compile. The preprocessor is typically abbreviated as PP in Unix tradition, and in an automated build script the C preprocessor is abbreviated as a macro reference for CPP. In order not to cause ambiguity, C + + (C-plus-plu
