What is the difference between template metaprogramming and runtime programming?

What is the difference between template metaprogramming and runtime programming?

Template metaprogramming is a technique in C++ where templates are used to generate code at compile time, while runtime programming involves executing code during the program's execution.

Can you give me an example of template metaprogramming?

Sure! A common example is using templates to create a compile-time factorial function, which calculates the factorial of a number during compilation.

What are the advantages of using template metaprogramming?

Template metaprogramming can lead to more efficient code, as it allows for optimizations at compile time, reducing runtime overhead.

Are there any downsides to template metaprogramming?

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

When should I choose runtime programming over template metaprogramming?

Choose runtime programming when you need flexibility and dynamic behavior that can't be determined at compile time.
