Conclusion
Explore a comprehensive overview of C++ template metaprogramming, from basic template definitions through advanced concepts such as variadic templates, SFINAE, and C++20 constraints. Understand practical patterns, idioms, and the use of templates in standard containers and algorithms. This lesson helps consolidate knowledge and encourages applying these skills to develop efficient and versatile C++ code.
We'll cover the following...
We are now at the end of this course. Templates are not the easiest part of C++ programming. Indeed, people usually find them difficult or horrendous.
However, templates are heavily used in C++ code, and it’s likely that whatever kind of code we’re writing, we’ll be using templates daily.
Core template concepts
We started the course by learning what templates are and why we need them. We then learned how to define function templates, class templates, variable templates, and alias templates. We learned about template parameters, specialization, and ...
