C++ Standard Template Library in Practice - Modules

The video introduces C20 modules, an experimental feature in C, explaining their role in managing user libraries and replacing the preprocessor. It details the structure of modules, including interface and implementation units, and the use of partitions. The video provides an example of module code, discusses compiler requirements, and demonstrates building and using modules with Clang 8. It emphasizes that modules are not yet ready for production use.

What is the main problem with C in terms of package management compared to languages like Ruby or Python?

• C has a built-in package manager.

• C is not well-suited to handle user libraries.

• C has too many package management systems.

• C uses a different syntax for package management.

What is the role of an interface unit in a module?

• It exposes the capabilities of the library using the 'exports' keyword.

• It provides the actual implementation of the library.

• It is a secondary entry point for the library.

• It is used to compile the module.

Which keyword is used to expose the capabilities of a module?

• import

• include

• define

• export

What is a limitation of the current compiler support for modules?

• Modules do not require any special flags.

• Modules can only be used in production code.

• Only two compilers currently support modules, and one must be built from source.

• All compilers support modules without any issues.

In the practical example, which compiler is used to work with modules?

• Clang 8

• Intel Compiler

• MSVC

• GCC

What is the purpose of the 'modules T' flag in the compilation process?

• It enables the use of templates.

• It optimizes the code for speed.

• It stands for modules technical specification.

• It is used for testing purposes.

What is the first step in the compilation process of a module?

• Compiling the module into a PCM file.

• Compiling the main program.

• Linking the object files.

• Running the executable.
