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++ 17 ?
The any class (std::any) is a new class defined in the <any> header in C++17 and it is used for any type…
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…
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 templates, and this feature makes template arguments more readable and concise. There are 4 different types of usage and in this…
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…
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 alternative to support older code. In this post, we list most of these mathematical functions declared in the <cmath>…
The features of C++17 were a big step in the history of C++ and brought a lot of new features. In C++17, there are new auto rules for direct-list-initialization. This feature in C++, changes the rules for auto deduction from a braced-init-list. In this post, we explain what…
In modern C++, namespaces are a kind of library or framework. They are useful to hold the same name of classes, methods, and other entities in different namespaces. C++11 standard and other standards above, allow the inline keyword in a namespace definition and in this post…
In C++, Classes and Objects are part of object-oriented methods and typically provide features such as properties and methods. One of the features of a C++ Editor are assignment operators such as copy assignment and move assignment operators. In C++, a copy assignment operator is used with “operator=” to create a new object from an existing one. In this post, we explain assignment…
