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 pointers, they came with C++11. The most used types of C++ smart pointer areunique_ptr, auto_ptr, shared_ptr, and weak_ptr.
The Aggregate Member Initialization is one of the features of C++. This feature is improved and modernized with C++11, C++14 and C++20. With this feature, objects can initialize an aggregate member from braced-init-list. In this post, we explain what the aggregate member…
Using multi-threading development skills on the CPU, GPU, and memory operations is important in programming, but it can give rise to problems in synchronization of multi-thread operations and reaching data for reading and writing. The concurrency support library in modern…
The concurrency support library in modern C++ is designed to solve problems in multi-thread operations. Since the C++11 standard, this library includes built-in support for threads (std::thread) with atomic operations (std::atomic). In this post, we explain two atomic operations that can be used with std::atomic types, we explain what are atomic addition and subtraction operations.
What is…
The concurrency support library in modern C++ is designed to solve problems in multi-thread operations. Since the C++11 standard, this library includes built-in support forthreads (std::thread) with atomic operations (std::atomic). In this post, we explain what two…
Since the C++11 standard, the concurrency support library inModern C++is designed to solve problems in multi-thread operations and is updated in every new standard. This library includes built-in support for threads (std::thread) with atomic operations…
In modern C++, the concurrency support library is designed to solve problems in multi-thread operations. This library includes built-in support forthreads (std::thread), atomic operations (std::atomic), mutual exclusion (std::mutex), condition variables (std::condition_variable),and many other features of a modern C++ compiler. In this post, we explain what is std::atomic and how we…
Unions are rarely used but are another important data type alternative to structs and classes in modern C++ development. Unions are used to define variables that share storage space. The C++11 standard loosens up the restriction regarding members of unions, and in this…
In C++, memory and CPU/GPU management are very important and the compiler is amazingly using them well in templates, classes, and objects. Every declaration and usage of any bits may cause a lot of heavy calculations, memory usage, and high CPU/GPU usage. Using copy and move…
In modern C++, rvalue references are a compound type like standard C++ references, which are referred to as lvalue references.New rvalue reference rules were set by the C++11 specifications. In many cases, data is copied that simply needs to be moved, that is, the original data holder need not retain the data. The rvalue reference can be used to distinguish cases that require copying versus…
