What are C++20 modules and how do they improve code organization?

C++20 modules are a new feature that allows you to organize code into separate units, improving compilation times and reducing dependencies.

Can you explain how modules differ from traditional header files?

Unlike header files, which can lead to multiple inclusions and longer compile times, modules provide a single interface and are compiled once, reducing redundancy.

What are the benefits of using modules in large projects?

Modules enhance encapsulation, reduce compile times, and improve code readability, making them ideal for large projects.

Are there any downsides to using C++20 modules?

One downside is that not all compilers fully support modules yet, which may limit their use in some environments.

How can I start using modules in my existing C++ projects?

You can start by refactoring your code to define modules, using the module keyword, and updating your build system to support them.
