What are the advanced features of C++ modules?

C++ modules offer features like improved encapsulation, better compile-time performance, and modularity. They help manage dependencies more effectively.

How do modules improve compile-time performance?

Modules reduce the need for repeated parsing of header files, allowing the compiler to process code more efficiently, which speeds up compilation.

Can you explain how to create a simple module?

Sure! To create a module, you define a module interface using the module keyword, then implement it in a separate file. For example:

// my_module.cppm
module my_module;
int add(int a, int b) { return a + b; }

You can then import this module in other files.

What are the benefits of using modules over traditional headers?

Modules provide better encapsulation, reduce name clashes, and improve build times by avoiding redundant inclusions, making code easier to manage.
