There is a lot of power in the strange-looking three dots that are heavily used in the Standard Template Library. Today, I visualize the expansion of the three dots and show a few use cases.
A variadic template is a template that can have an arbitrary number of template parameters. This feature may seem magical to you if you see it the first time. So, let me demystify variadic templates.
Template instantiation is the creation of a concrete function or a concrete class out of a function template or class template. The creation of template instantiation can be implicit (compiler-generated) or explicit (user-provided).
I'm happy to present the five winners in this post including their answers.
I presented in my last post "Parallel Algorithms of the STL with the GCC Compiler" the necessary theory about the C++17 algorithm. Today, I make a performance test using the Microsoft compiler and the GCC compiler to answer the simple question: Does the execution policy pay off?
GCC supports my favorite C++17 feature: the parallel algorithms of the Standard Template Library (STL). I recognized this a few days ago, and I'm happy to write a post about it and share my enthusiasm.
I give away five vouchers for Stephan Roth's book "Clean C++20", sponsored by the book's publisher Apress.
As you may know from my previous post Template Specialization, function template can only be full but not partial specialized. To make my long story short: Don't specialize function templates. Just use function overloading.
After I presented in my last post Template Specialization the basics about template specialization, I dig today deeper. I want to present the partial and full specialization of a class template as a compile-time if.
Templates define the behavior of families of classes or functions. Often it is required that special types or non-types may be treated special. To support this use case, you can specialize templates.
