Containersare powerful data storage arrays in modern C++ and they are very useful to iterate and search data with their amazing methods and properties. A container is a holder object that stores data elements (a collection of data objects). std::vector, std::array, std::set are these kinds of containers. There is another useful container, in this post, we explain what std::list is. Before…
What Are The Differences Between std::rand() And std::mt19937 In Modern C++?
February 2, 2024
Random numbers are widely used in today’s modern applications. In C we use rand(), srand() and in C++ it is std::rand(), std::srand(). Since C++11, we can use the Mersenne Twister random generators; mt19937 (std::mt19937) for 32-bit applications and mt19937_64…
Random numbers are one of the most important parts of today’s modern programming technologies. They are used in mathematics, physics, in many engineering fields, and in programming such as generating random data for testing, random maps in levels, random trees on a…
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…
Solving C++ optimization problems are one of the areas of all quantitative disciplines from social science, economics to engineering fields such as computer science. Genetic Algorithm (GA) is a kind of machine learning process that is used to generate high-quality…
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 class template std::variant in C++ 17?
The std::variant is a class template defined in <variant> header that…
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…
C++17 standard is amazing with a lot of new features, and one of the interesting features was the new type std::any. std::any is a type-safe container to store a single value of any variable type. In this post, we explain std::any in modern C++.
What is std::any in C++ 17 ?
The any class (std::any) is a new class defined in the <any> header in C++17 and it is used for any type…
