What Is The disjunction (std::disjunction) Metafunction In C++?

Metaprogramming is another great feature of modern C++ that allows programs to redesign themselves during compilation or run time. In C++17, another new feature of 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 explain…

What Is Set (std::set) In Modern C++?

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.

What Are The Differences Between std::rand() And std::mt19937 In Modern C++?

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 (std::mt19937_64) for 64-bit applications. Modern C++ allows us to use both old and new random generators. In this post, we explain…

Everything You Need To Know About The Copy Assignment Operator In C++ Classes

Classes and Objects are part of object-oriented methods and typically provide features such as properties and methods. One of the great features of an object orientated language like C++ is a copy assignment operator that is used with operator= to create a new object from an existing one. In this post, we explain what a copy assignment operator is and its types in usage with some C++…
