A study of several issues found with static analysis
Posted on
The static analysis of our code base has identified lately several several issues in the C++ code that I had to fix. Once again, this help me I realize how it is to make mistakes that are usually hard to find by just looking at the code (with a human eye). I believe it is…
Three new utility functions in C++23
Posted on
Some time ago I wrote a blog post called Three C++23 features for common use. In this article, I want to continue on that idea and discuss three new utility functions that were added to C++23.

Using the C++23 std::expected type
Posted on
The C++23 standard will feature a new utility type called std::expected. This type either contains an expected value, or an unexpected one, typically providing information about the reason something failed (and the expected value could not be returned). This feature is, at this time, supported in GCC 12 and MSVC 19.33 (Visual Studio 2022 17.3)….
requires expressions and requires clauses in C++20
Posted on
The C++20 standard added constraints and concepts to the language. This addition introduced two new keywords into the language, concept and requires. The former is used to declare a concept, while the latter is used to introduce a requires expression or a requires clause. These two could be confusion at first, so let’s take a…
Unwrapping WinUI3 for C++
Posted on
The Windows UI Library 3, known shortly as WinUI 3, is a native UI framework that ships with the Windows App SDK. This is an SDK complementary to the Windows SDK, WPF, WinForms, and Win32. It provides a new unified set of APIs and tools that can be used to develop desktop apps on Windows 11 (as well as downwards to Windows 10, version 1809). I decided to have a look at what this framework provides and this post is written as I am trying it. To evaluate it, I’ll try to build a small application that does conversion between Celsius and Fahrenheit degrees as you type in a field.
New C++23 range adaptors
Posted on
The C++23 standard provides several new range adaptors in the ranges library. These include join_with, zip, and zip_transform. In this post, I will briefly show how these should work.
What has the standard committee ever done for us?
Posted on
Every time I see people complaining on social media about the C++ standard committee not going this or that I remember the famous scene from the movie Live of Brian when the Jews debate the benefits of the Roman occupation. However, put into the C++ world, the scene would be as follows:
Finding the second largest element in a range
Posted on
In recent days, there’s been a question coming up on twitter: how do you find the second largest element in an array (container)? People are providing different answers. As usual, there are multiple solutions to this problem and they depend on the actual requirements: could this operation have side effect (change the original range) or should it be left untouched? In this post, I will discuss several solutions in C++ to this problem.
