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 header that represents a…
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…
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 is a class template that is defined in the header and represents either a T value or no value. In this post, we explain, what is…
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 traits.
What is a…
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++…
The C++17 standard came with a lot of new features and improvements. One of the features was the math.h library which modernized math operations with the cmath library. The Parallelism Technical Specification adds several new algorithms to the standard C++ library that we…
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 now part of modern C++ and are implemented in the filesystem library.
What Is the filesystems library in C++ 17?

In C++14, there are pretty good new overloads of std::equal, std::mismatch, and std::is_permutation that can be used to take a pair of iterators for the second range. They can be used with the new C++ Builder 12 along with the 11.x, or 10.x versions too. In this post, we…
C++14 brought us a lot of useful things that we use today. One of the great features of C++14 was the member initializers and aggregates feature that a class with default member initializers may now be an aggregate. In this post, we explain how can use member initializers…
Iterators are one of the most useful features of containers in modern C++. Mostly we use them with vectors, maps, strings, and other containers of C++. In C++11, the begin() and end() iterators are used to define the start of iteration and the end of the iteration, mostly used in the for loops. In C++14, there are new additions to the global std::begin – std::end functions, and in this post, we…
