What are some advanced features in C++ and Java?

In C++, advanced features include templates, smart pointers, and the Standard Template Library (STL). In Java, you have features like generics, annotations, and the Stream API.

Can you explain how templates work in C++?

Templates in C++ allow you to write generic and reusable code. You can create functions and classes that work with any data type.

What about generics in Java? How do they differ from C++ templates?

Generics in Java provide type safety at compile time and allow you to define classes and methods with type parameters. Unlike C++ templates, Java generics use type erasure, meaning the type information is not available at runtime.

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

Yes, C++ templates can lead to more optimized code since they are resolved at compile time, while Java's generics may introduce some overhead due to type erasure.
