Metaprogramming is another great feature of modern C++ that allows programs to redesign itself during compilation or run time. In C++17, another new feature about metaprogramming is introduced, logical operation metafunctions. These are variadic metafunctions that are conjunction, disjunction, and negation which can be used for metaprogramming features of applications. In this post, we…
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…
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…
C++17 is another big milestone in the history of C++, it comes with a lot of new features. In C++17, the fold expressions feature is a powerful feature that allows us to fold a parameter pack over a binary operator. Folding Expressions are very useful with variadic templates, and this feature makes template arguments more readable and concise. There are 4 different types of usage and in this…
The template is one of the great features of modern C++. They are a simple and very powerful statement in C++ that defines the operations of a class or function. The C++14 standard and above allows the creation of variables that are templated. In this article, we will…
In modern C++, the concurrency support library is designed to solve problems in multi-thread operations. This library includes built-in support forthreads (std::thread), atomic operations (std::atomic), mutual exclusion (std::mutex), condition variables…
In a modern C++ code compiler, there are many features that help you learn, master, and remember the various features and functions of the C++ language. One such feature of modern C++ is the move constructor that allows you to move the resources from one object to another without copying them. The C++11 standard provides an alternative to std::move, which is std::move_if_noexcept, to solve some…
In C++, memory and CPU/GPU management are very important and the compiler is amazingly using them well in templates, classes, and objects. Every declaration and usage of any bits may cause a lot of heavy calculations, memory usage, and high CPU/GPU usage. Using copy and move…
The Move Constructor is one of the great features of Object Oriented Programming in C++, such as other features like; copy assignment operator constructors, copy constructors, move assignment operators, destructors, etc. Since the C++11 standards, inmodern…
When there is a numerical value in an application’s development code, a professional programmer needs to understand which type of a variable should be used how big it could be in terms of capacity and memory usage. The developer must take into account what the minimum and maximum ranges could be. In most operations, the exact choice of variable might not be too important, but for larger…
