About code. Mostly on C++
The Visual Studio editor has lots of functionalities, many of them available with the use of shortcuts. In this post, I will share several that I find very useful and I use quite often. This post refers to Visual Studio 2019.
Back in mid-August, Microsoft released the 2nd preview of Visual Studio 2019 16.3. This is the first version of Visual Studio to support concepts from C++20 both in the compiler and the standard library (header <concepts>) without the changes made at the ISO C++ standards meeting in Cologne. These changes are available when you compile with the /std:c++latest switch.
Concepts allow performing compile-time validation of template arguments and function dispatch based on properties of types. Concepts are very useful in libraries where they can be used to impose compile-time checks on the template arguments of functions or types. For instance, a generic algorithm for sorting a container would require the container type to be sortable for the program to even compile.
In this article, I will show an example with a concept that verifies that a type T can be converted to a std::string via a to_string() function, that is either a member of the class or a free function.
Visual Studio 2017 has had a larger number of updates throughout its lifetime. At the time of writing this article, there have been ten major updates and countless minor ones. You can check the release notes history for details. Part of the changes was in the debugger. In this article, I will mention three features…
The first preview version of Visual Studio 2019 is available since the beginning of December 2018. I decided to take a look to see what is different from the previous Visual Studio 2017 version. In this post, I will present some of the things that are new or changed in this new version.
