A concurrency support library is designed to solve problems in modern C++ that arise with multi-thread development. This library includes built-in support for threads (std::thread), atomic operations (std::atomic), mutual exclusion (std::mutex), condition variables (std::condition_variable), and many other features. In C++14, in addition to mutex, there is a shared_mutex which is an instance of…
Sometimes we want to preserve the string format especially when we use string in a string with /”. In C++14 and above, there is a std::quoted template that allows handling strings safely where they may contain spaces and special characters and it keeps their formatting…
Allocating memory and freeing it safely is hard if you are programming a very big application. In Modern C++ there are smart pointers that help avoid the mistake of incorrectly freeing the memory addressed by pointers. Smart pointers make it easier to define and manage…
In C++, the constexpr specifier is used to declare a function or variable to evaluate the value of at compile time, which speeds up code during runtime. This useful property had some restrictions in C++11, these are relaxed in C++14 and this feature is known asRelaxed Constexpr Restrictions. In this post, we explain what are the relaxed constexpr restrictions in modern C++.
What is the…
The template is one of the great features of modern C++. They are a simple and very powerful statement in C++ that defines the operations of a class or function. The C++14 standard and above allows the creation of variables that are templated. In this article, we will…
Lambda Expressions allow users to write an inline expression that can be used for short snippets of code in your C++ app which are not going to be reused and don’t require naming. The Lambda Expression construct is introduced in C++ 11 and further developed in the C++14…
Modern C++ has a lot of useful functions coming from C. One of them was the gets() function that we use to get string inputs and that we were able to use in C++11 or earlier. In C++14, the gets function was removed, while fgets or other input functions remain there. If you have older C++ code that uses the gets() functions your C++14 version compiler will not compile it. Why was the gets function…
C++ is very strong in every aspect of modern programming. Volatile types are used with the volatile keyword. It is a lesser known type qualifier that is important to read types or objects whose value can be modified at any time. The volatile keyword is useful in…
Since the C++11 standard, the Concurrency Support Library includes built-in support for threads (std::thread) with atomic operations (std::atomic). C++11 provides both weak and strong compare-and-exchange operations in multi-threading applications. Since C++11, weak compare…
Since the C++11 standard, the Concurrency Support Library includes built-in support for threads (std::thread) with atomic operations (std::atomic). C++11 provides both weak and strong compare-and-exchange operations in multi-threading applications. Since C++11, strong compare and exchange are used in modern C++ standards such as C++14, C++17, C++20, and in other new standards. In this post, we…
