What is the difference between template metaprogramming and runtime programming?

What is the difference between template metaprogramming and runtime programming?

Template metaprogramming is a compile-time technique that generates code based on templates, while runtime programming involves executing code during program execution.

Can you give me an example of template metaprogramming?

Sure! In C++, template metaprogramming can be used to create a function that computes factorials at compile time using templates.

What are the advantages of using template metaprogramming?

Advantages include improved performance, type safety, and the ability to generate highly optimized code.

Are there any downsides to template metaprogramming?

Yes, it can lead to longer compile times and more complex error messages, making debugging harder.

When should I choose runtime programming over template metaprogramming?

Choose runtime programming when you need flexibility, dynamic behavior, or when working with types that are not known until runtime.
