The most powerful data storage arrays inModern C++areContainersand they are very useful to iterate and search members 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::list are these kinds of containers. There is another useful containerstd::dequethat…
Modern C++is very powerful with many great features to help you write programs more easily with safer template class objects that have faster algorithms and methods. In C++, Containersare the powerful data storage arrays in modern C++ and they are very useful for…
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 planet – the list is endless. Since C++11, mt19937 (std::mt19937) is implemented as a random number generator. In this…
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…
Everything You Need To Know About The Copy Assignment Operator In C++ Classes
January 4, 2024
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…
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…
In programming, one of the most used variable types are text strings, and they are sometimes really important when storing and retrieving valuable data. It is important to store your data safely in its language and localization. Most programming languages have issues when…
In C++11 and C++14, we were able to use this math.h library in C++ applications. After the C++17 standard, this library is modernized in the cmath library, and functions are declared in <cmath> header for compatibility reasons in modern C++, and the <math.h> is an…
C++11 introduced new forms of literals using modified syntax and semantics to provide User-Defined Literals (UDL) also known as Extensible Literals. While there was the ability to use them the standard library did not use any of them. In C++14, the commission added some standard literals. In this post, we explain user-defined literals operators and we explain some of these standard literals…
