Modern C++ has a lot of options to add and modify data members with its amazing data holders, arrays, structs, pointers, and containers. Containers are powerful data storage arrays in C++ and they are very useful to iterate and search. A container is a holder object that stores data elements (a collection of data objects). std::array, std::vector, and std::map are these kinds of containers.

In C++ 17, there is a very useful alias template for metaprogramming that can be used to simplify use of SFINAE. The void_tis a meta-function that is used to map any types ( or types) to typevoid. In this post, we explain what is void_t, how you can use it in different examples.
What is alias template void_t in C++ 17?
The void_t is an alias template which is introduced with…
There is a new library feature in the C++17 standard, it is std::invoke which is a useful feature to uniformly invoke callable entities. In this post, we explain what std::invoke is and how we can use it in examples. First, let’s remind ourselves about what is a…
In addition to many beneficial features of C++ 17, there are elementary string conversions introduced in that specification. The std::to_chars() and std::from_chars() are defined in <charconv> header to do conversions between numeric values to strings or strings to…
The C++ 17 standard bring us a lot of useful methods, templates and algorithms. One of the great algorithms is std::sample defined in the <algorithm> header that samples at most n elements uniformly from a given range. In this post, we explain the std::sample algorithm and how we can use it with an mt19937 random generator.
What is the std::sample algorithm in C++ 17 and beyond?
The…
In C++ Builder 12, and modern C++ the std::variant is one of the powerful features that comes with C++17. The std::variant is a discriminated union that we can work with multiple data types. It represents a type-safe union and holds one of its types in definition.
What is…
The C++17 standard came with a lot of great features and std::optional was one of the main features of today’s modern C++. std::optional<T> is a class template that is defined in the <optional> header and represents either a T value or no value. In this post…
One of the great features of C++ is templates, they are parameterized by alias templates in C++11. Then, In C++14 and C++17, they improved C++11’s feature with a number of template aliases whose use simplifies the traits. This feature is called “Alias Templates For Traits” and in this post, we explain what is and alias template and how we can use alias templates with…
