What are some advanced C++ templates and their use cases?

Advanced C++ templates allow for powerful metaprogramming techniques. For example, template specialization can optimize code for specific types.

Can you explain template specialization with an example?

Sure! Template specialization allows you to define a specific implementation for a particular type. For instance, you can have a general template for a function and then specialize it for int types to handle them differently.

What about variadic templates? How do they work?

Variadic templates enable you to create functions that accept any number of template parameters. This is useful for creating flexible and reusable code, like a function that can sum any number of arguments.

Are there any performance considerations with using templates?

Yes, while templates can lead to more optimized code, they can also increase compile times and binary sizes due to code bloat. It's essential to balance their use.
