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 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 and aggregates with examples.
What are the member initializers and aggregates features in C++14?
With the new C++14, a…
In modern programming sometimes we want to use a sequence of integers that are created at compile-time. In C++14, the std::integer_sequence is a class template for the sequence of integers that is generated at compile-time. In this post, we explain what integer sequence…
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…
In C++11, the final specifier is used for a function or for a class that cannot be overridden by derived classes, and there was no way to check if that class or method is the final. In C++14, there is a std::is_final type trait that can be used to detect if a class or a method is marked as a final or not. In this post, we explain how we can use the std::is_final type trait in C++14 and…
Modern C++ has base class features that can be used with other modern features of C++. The std::integral_constant is the base class for the C++ type traits in C++11, and in C++14, std::integral_constant gained an operator () overload to return the constant value. In this…
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…
Containers are data storage arrays in modern C++ and they are very useful to iterate and search data with their amazing methods and properties. The C++ Standard Library defines four different main container types and one of them is associative containers such as std::map, and std::set. These class types allow us to use the look-up method “find()” by a value based on a value of that…
