What are some advanced techniques for using templates in programming?

Advanced template techniques include template specialization, variadic templates, and SFINAE (Substitution Failure Is Not An Error). Would you like to dive deeper into any of these?

Can you explain template specialization?

Template specialization allows you to define a specific implementation of a template for a particular type. This is useful when you need different behavior for certain types.

What is SFINAE?

SFINAE stands for Substitution Failure Is Not An Error. It allows you to enable or disable template instantiations based on whether certain conditions are met, which is useful for creating more flexible templates.

How do variadic templates work?

Variadic templates allow you to create templates that accept an arbitrary number of template parameters, making them very powerful for functions that need to handle multiple types.

Can you give an example of using variadic templates?

Sure! A common example is a function that can take any number of arguments and print them. You can use a variadic template to achieve this.
