What are some advanced features in C++ and Python that I should know about?

In C++, features like smart pointers, templates, and the Standard Template Library (STL) are essential. In Python, decorators, generators, and context managers are quite powerful.

Can you explain how smart pointers work in C++?

Smart pointers in C++ manage memory automatically. They help prevent memory leaks by ensuring that memory is freed when it's no longer needed. Examples include std::unique_ptr and std::shared_ptr.

What about decorators in Python? How do they enhance functions?

Decorators in Python allow you to modify or enhance functions or methods without changing their code. They are often used for logging, access control, and caching.

Are there any performance differences between these features in C++ and Python?

Yes, C++ generally offers better performance due to its compiled nature and low-level memory management. Python, being interpreted, may have slower execution but provides ease of use and rapid development.
