In order to compile C++ templates the compilers like Embarcadero RAD Studio C++ compilers are required to perform two stages: definition stage and instantiation stage.
The template definition stage
On this stage the following checks are performed:
static assertions and availability of names declarations (such as names of classes and functions) independent on template parameters are…

If you are on the hunt for the best C/C++ compilers available today, this article lists the top C/C++ compilers for Windows with their features. It’s very hard, in fact, to identify which C++ compiler is the best for you, as this is mostly about what you want to…
An integrated development environment (IDE) is a software application that provides a complete set of features for application development. Code is generally written in text format, and you can easily edit or modify your code using text editors like Notepad, Word, Wordpad, etc. For a developer (beginner or professional), however, an IDE is really important because features like highlights, auto…
Learn C++ With The Future of C++ Parallel and Concurrency Safety Guidelines by Michael Wong and Ilya Burylov (CppCon 2020) Video
November 28, 2020
The guidelines for safe parallel/concurrency C++ has never been established. It is a challenge that has taken the most of time, especially with the constant change of the C++ standard. This video talks about the developing rules, which has yet to be finalized, but can give…
This video gives you a quick introduction to the RAD Studio and C++Builder IDE for quickly building beautiful Windows apps with C++. Eli M. walks you through how to set up both VCL and FireMonkey projects while going through some of the key IDE features. C++Builder is a…
Learn C++ With Template Metaprogramming: Type Traits by Jodi Haggins (CPPCon 2020) Video
November 26, 2020
Template metaprogramming can be very broad. However, fundamental idioms exist and can be found useful with the modern C++ code. This video focuses on applying type traits from the standard library, as having knowledge in the fundamental idioms of template metaprogramming can…
There are two kinds of if statements in modern C++: runtime if and compile-time if constexpr.
Runtime if looks like:
if (condition) statement-true
if (condition) statement-true else statement-false
In both forms of above if the result of…
Learn The Initialization Of Class Objects By Rvalues When Building Windows Apps In C++
November 25, 2020
C++Builder includes the use of rvalue references, which allow creating a reference to temporaries. When you initialize to an class object using an rvalue(a temporary object), C++11 looks to see if you have defined a move constructor in your class. If you have, the temporary object is passed to it as a modifiable (non-const) rvalue reference, allowing you to transfer ownership of resource pointers…
