What are the best practices for SFINAE in C++?

What are the best practices for SFINAE in C++?

SFINAE, or Substitution Failure Is Not An Error, is a powerful feature in C++. Best practices include using it for template specialization and type traits.

Can you give an example of SFINAE in action?

Sure! Here's a simple example: you can use std::enable_if to enable a function only if a certain condition is met, like checking if a type is integral.

What are common pitfalls to avoid with SFINAE?

Common pitfalls include overusing SFINAE, which can lead to complex and hard-to-read code, and not providing clear error messages.

How does SFINAE compare to other template metaprogramming techniques?

SFINAE is often preferred for its clarity and flexibility compared to techniques like tag dispatching, which can be more cumbersome.
