What are some advanced composition techniques in C++?

Advanced composition techniques in C++ include using smart pointers, composition over inheritance, and the decorator pattern.

Can you explain how smart pointers work in composition?

Smart pointers, like std::shared_ptr and std::unique_ptr, manage memory automatically, preventing leaks and ensuring proper resource management.

What is the decorator pattern and how is it used in C++?

The decorator pattern allows behavior to be added to individual objects, either statically or dynamically, without affecting other objects.

Are there any performance considerations with these techniques?

Yes, while these techniques improve code safety and maintainability, they can introduce overhead, so profiling is essential.
