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…
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…
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++…
C++17 had enormous changes in C++ features. One of them was basic_string_view (std::basic_string_view) which is a constant string container that can be used for multiple string declarations. The basic_string_view is a modern way of read-only text definition. It can be used by iterators and other methods of the basic_string_view class. In this post, we explain basic_string_view and its…
With the C++17 standard, the contents of the Parallelism Technical Specification are added to modern C++, and as a result, make their way into many C++ compilers and IDEs, such as the latest C++ Builder 12. This feature adds new overloads, taking an additional execution…
In modern C++, the filesystem library allows portable interaction with directories and directory-like structures providing functions such as listing directory contents and moving files. After the C++17 standard, the contents of the Filesystems Technical Specification are…
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 storing texts and letters. In C++, there is very old well-known string type (arrays of chars) and modern types…
When Is The CMath Mathematical Special Functions Header Used in Modern C++?
December 1, 2023
The math library <math.h> in C language is designed to be used in mathematical operations. From the first C language to the latest C++ Builder 12, there have been many changes and improvements in both hardware and software. We were able to use this math.h library in…
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 modernized math operations with the cmath library. Functions are declared in <cmath> header. For compatibility reasons the <math.h> is an optional…
Unions are rarely used but are another important data type alternative to structs and classes in modern C++ development. Unions are used to define variables that share storage space. The C++11 standard loosens up the restriction regarding members of unions, and in this post, we explain the unrestricted unions feature that came with C++11.
What is a union in modern C++?
Unions are used to…
