In a modern C++ code compiler, there are many features that help you learn, master, and remember the various features and functions of the C++ language. One such feature of modern C++ is the move constructor that allows you to move the resources from one object to another without copying them. The C++11 standard provides an alternative to std::move, which is std::move_if_noexcept, to solve some…
CPUs and GPUs have evolved year on year to feature a greater number of cores and transistors to give more computational power for today’s servers and computers. With the advent of multiple cores, it is common now for programs to make use of multiple simultaneous…
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 types in templates is very important when you develop a professional app. In this post, we explain how you can use…
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…
In modern C++, explicit-qualified conversion functions work in the same context as explicit-qualified constructors and produce diagnostics in the same contexts as constructors do. C++11, C++17, and C++20 standards have improvements in this explicit specifier. This is done to…
In modern C++, explicit-qualified conversion functions work in the same context as explicit-qualified constructors and produce diagnostics in the same contexts as constructors do. C++11, C++17, and C++20 standards have improvements in this explicit specifier. This is done in order to avoid situations when the compiler uncomplainingly accepts code that is not semantically correct. In this post, we…
In programming, some of the most important parts are the functions that we create. They are like Lego parts that we can use in all places of the application. In modern C++ development, a function declaration is really important, and these functions gained some additional…
In modern C++ software, a virtual function is a function in a base class or struct that can be redefined in derived classes or structs. They are member functions whose behavior can be overridden in derived classes. Thevirtual function specifier is the…
In C++, the for loops are one of the great features of C and C++ language that has many options to break, continue, or iterate in a loop. In modern C++, there is a range-based for loop that makes it simple to iterate through a variable type that has members (i.e. strings, lists, arrays, vectors, maps, etc.). The range-based for loop is a feature for the for() loops introduced by the C++11…
