What are some examples of C++ metaprogramming?
C++ metaprogramming allows you to write code that generates code at compile time. Examples include template metaprogramming, type traits, and constexpr functions.
Can you explain template metaprogramming with an example?
Sure! Template metaprogramming uses templates to perform computations at compile time. For instance, you can create a template to calculate factorials.
How does constexpr work in metaprogramming?
constexpr
allows you to evaluate functions at compile time. This can optimize performance by reducing runtime calculations.
What are the benefits of using metaprogramming in C++?
Benefits include code reusability, type safety, and performance improvements by shifting computations to compile time.
