C++ Stories

std::expected from C++23 not only serves as an error-handling mechanism but also introduces functional programming paradigms into the language. In this blog post, we’ll have a look at functional/monadic extensions of std::expected, which allow us to...

In the article about std::expected, I introduced the type and showed some basic examples, and in this text, you’ll learn how it is implemented.
A simple idea with struct
In short, std::expected should contain two data members: the actual expected value and the unexpected error object. So, in theory, we could use a simple structure:...

In this article, we’ll go through a new vocabulary type introduced in C++23. std::expected is a type specifically designed to return results from a function, along with the extra error information.
Motivation
Imagine you’re expecting a certain result from a function, but oops… things don’t always go as planned....

Thanks to the powerful constexpr keyword and many enhancements in recent C++ standards, we can now perform a lot of computations at compile time. In this text, we’ll explore several techniques for parsing integers, including the “naive” approach, C+...
