Full Specialization of Function Templates

12 July 2021

As you may know from my previous post, Template Specialization, a function template can only be full but not partially specialized. To make my long story short: Don't specialize function templates. Just use function overloading.

Template Specialization - More Details About Class Templates

Templates define the behavior of families of classes or functions. Often it is required that particular types or non-types may be treated special. To support this use case, you can specialize templates.

Template Argument Deduction of Class Templates

17 June 2021

In my last post, Template Arguments, I wrote about function template type deduction (C++98) and auto type deduction (C++11). Today I wear more modern hats. I start with automatic type deduction of non-type template parameters and class templates (C++17) and finish with automatic type deduction of concepts (C++20).

Template Arguments

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).

Alias Templates and Template Parameters

7 June 2021

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.

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.
