module in C++

1. 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.[1] 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..

2. Single Compilation Unit

Single Compilation Unit (SCU) is a computer programming technique for the C and C++ languages, which reduces compilation time for programs spanning multiple files. Specifically, it allows the compiler to keep data from shared header files, definitions and templates, so that it need not recreate them for each file. It is an instance of program optimization. The technique can be applied to an entire program or to some subset of source files; when applied to an entire program, it is also known as a unity build..

4. Overview of modules in C++

This is a paragraphC++20 introduces modules, a modern solution for componentization of C++ libraries and programs. A module is a set of source code files that are compiled independently of the translation units that import them. Modules eliminate or greatly reduce many of the problems associated with the use of header files, and also potentially reduce compilation times. Macros, preprocessor directives, and non-exported names declared in a module are not visible and therefore have no effect on the compilation of the translation unit that imports the module. You can import modules in any order without concern for macro redefinitions. Declarations in the importing translation unit do not participate in overload resolution or name lookup in the imported module. After a module is compiled once, the results are stored in a binary file that describes all the exported types, functions and templates. That file can be processed much faster than a header file, and can be reused by the compiler every place where the module is imported in a project..

7. C++ Language Reference

This reference explains the C++ programming language as implemented in Microsoft Visual C++. The organization is based on The Annotated C++ Reference Manual by Margaret Ellis and Bjarne Stroustrup and on the ANSI/ISO C++ International Standard (ISO/IEC FDIS 14882). Microsoft-specific implementations of C++ language features are included..

8. two C++ module questions

Greetings Kind Regards May I please inquire do C++ modules solve the problem of circular dependency Also how in the world can a templated class or function be contained in a module since its' template type parameters are not know until called from the importing file Thank You Kindly - Cheerio.
