Lesson plan
Translation unit (programming)
In C and C++ programming language terminology, a translation unit (or more casually a compilation unit) is the ultimate input to a C or C++ compiler from which an object file is generated. A translation unit roughly consists of a source file after it has been processed by the C preprocessor, meaning that header files listed in #include directives are literally included, sections of code within #ifndef may be included, and macros have been expanded. A C++ module also comprises a single translation unit, though while in a module #include directives will be expanded, import statements do not undergo expansion and thus are not.
