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 post, we explain the unrestricted unions feature that came with C++11.

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 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 ‘virtual’ specifier to declare avirtualfunction in a base class. In this post, we explain how we can use virtual…
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.
Modern C++ has many additions compared to the original C++ standard. Regarding virtual overrides, C++11 tends to tighten the rules, to detect some problems that often arise. To achieve this goal C++11 introduces two new contextual keywords, the final and the override…

To achieve this goal C++11 introduces two new contextual keywords, the final and the override specifiers.

In modern C++ the standards have a wonderfully named extended friend declaration feature to address the class declarations which is a template parameter as a friend. This extended friend declaration is available with the C++ compiler that has C++11 and above standards. In…
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, we explain how to use inline namespaces in modern C++.
