How can template metaprogramming improve performance in C++?

How can template metaprogramming improve performance in C++?

Template metaprogramming allows for compile-time computations, reducing runtime overhead and enabling optimizations.

Can you give an example of how this works in practice?

Sure! For instance, using templates, you can create a factorial function that computes values at compile time, avoiding runtime calculations.

What are the potential downsides of using template metaprogramming?

The downsides include increased compilation times and more complex error messages, which can make debugging harder.

Are there any best practices for using template metaprogramming effectively?

Yes, keep templates simple, avoid deep template recursion, and use type traits to improve readability and maintainability.
