What are the performance implications of using templates in programming?

What are the performance implications of using templates in programming?

Using templates can lead to code bloat, as each instantiation generates new code. However, they can also optimize performance by enabling compile-time polymorphism.

Can you explain how templates affect compile time?

Templates can increase compile time significantly because the compiler needs to generate code for each template instantiation. This can slow down the build process.

Are there any scenarios where templates might be detrimental to performance?

Yes, in cases of excessive template instantiation or when using complex template metaprogramming, it can lead to longer compile times and larger binary sizes.

How do templates compare to traditional inheritance in terms of performance?

Templates often provide better performance than traditional inheritance because they allow for static polymorphism, reducing the overhead associated with virtual function calls.
