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…
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…
In addition to many beneficial features of C++ 17, there are elementary string conversions introduced in that specification. The std::to_chars() and std::from_chars() are defined in <charconv> header to do conversions between numeric values to strings or strings to…
The C++ 17 standard bring us a lot of useful methods, templates and algorithms. One of the great algorithms is std::sample defined in the <algorithm> header that samples at most n elements uniformly from a given range. In this post, we explain the std::sample algorithm and how we can use it with an mt19937 random generator.
What is the std::sample algorithm in C++ 17 and beyond?
The…
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…
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 can use in C++ Builder 12. These are modernized in the <algorithm> header in the standard library. In this post, we…
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…
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…
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 explain these new overloads that we use ranges of iterations.
What are the new overloads for ranges in C++ 14?
In…
