How do I structure modules for large projects?

When structuring modules for large C++ projects, it's important to maintain a design that promotes organization, readability, and maintainability. A modular approach helps in breaking down the project into smaller, manageable components. Below is an overview of how to properly structure your C++ modules.

  • Header Files (.h): Define interfaces and declarations for your classes and functions.
  • Source Files (.cpp): Implement the logic of the classes and functions declared in header files.
  • Namespaces: Use namespaces to avoid naming conflicts and group related functions/classes.
  • Directory Structure: Organize your files into directories based on functionality, such as /src, /include, and /tests.
  • Build System: Utilize build systems like CMake or Make to manage dependencies and streamline the build process.

Here's an example of how to structure a simple C++ project:

// Example structure for a simple C++ project my_project/ ├── CMakeLists.txt ├── include/ │ └── my_module.h ├── src/ │ └── my_module.cpp └── tests/ └── my_module_tests.cpp

C++ modules project structure header files source files namespaces directory organization CMake
