It is pretty interesting how the compiler deduces the types for the template arguments. To make it short, you get most of the time the type you expect. The rules do not only apply to function templates (C++98) but also to auto (C++11), to class templates (C++17), and concepts (C++20).
Today, I write about two topics: alias templates and template parameters. Alias templates are a way to give a name to a family of types. Template parameters can be types, non-types, and templates themselves.
I am happy to announce. I updated my “Concurrency with Modern C++” book to C++20. This update includes a restructuring of the book and more than 50 pages and runnable examples. Now, you get about 650 pages of concurrency in C++ and nearly 200 runnable examples. Here is more info: https://leanpub.com/concurrencywithmodernc
In my last post, “Class Templates“, I presented the basics. Today, I may surprise you with the inheritance of class templates and the instantiation of member functions of class templates.
A function template represents a family of functions. Accordingly, a class template represents a family of classes. Today, I want to introduce class templates.
Now, it’s time to choose the next pdf bundle? Get all the material to your chosen topic.
In the last post, “Function Templates“, I wrote about the overloading of function templates and automatically deducing the return type of a function template. Today, I dive deeper and explicitly specify a function template’s arguments and bring concepts into the play.
A function template is a family of functions. In this post, I want to dive deeper into function templates.
The idea of this post is quite simple. I want to visualize templates and, in particular, the template instantiation process. Thanks to C++ Insights, this visualization is pretty straightforward.
I have two great news. First, you have my C++20 on Amazon and second, you can download the source code on GitHub.
