I’ve recently started writing C++ code and I want to ensure I’m following best practices. I have previous experience writing C# programs using a 3-layer architecture (presentation layer, business logic layer, and data access layer).

In C++, I’m aware of separating code into header files (.h) and implementation files (.cpp), but I’m unsure how to properly structure my project to keep my main function clean and organized. Specifically:

How should I separate the logic into different layers in C++?
Is there a standard way to organize files into directories?
Are there specific design patterns or best practices I should follow?
Here’s what I’ve tried so far:

I have separated my code into header (.h) and implementation (.cpp) files.
I’m considering organizing my files into different folders but I’m not sure if this is the best approach.
Any advice or examples would be greatly appreciated!

Thank you!
