From dynamic container operations to compile-time constants, C++ offers a variety of techniques (as in this famous Meme :)). In this article, we’ll delve into advanced initialization methods likereserve() and emplace_backfor containers to tuples with piecewise_construct and forward_as_tuple. Thanks to those techniques, we can reduce the number of temporary objects and create variables more efficiently.

In this article, we’d shed some light on the implementation of ranges::reverse_view and std::views::reverse. We’ll compare them to understand the differences between views and their adaptor objects. Let’s jump in. ranges::reverse_view and std::views::reverse in Action   Let’s look at an example to understand how these views work. Assume we have a range r of integers from 1 to 5.

Lots of practical examples, general programming, software development techniques, OOP, parallel algorithms, plus C++ to combine it all into working applications. This is a short introduction to the book “Introduction to Programming with C++” by Prof. Boguslaw Cyganek, an excellent book for students who start their journey with system coding.

In my last article, we discussed Finite State Machines based on std::variant and some cool C++17 techniques. Today I want to go further and show you an example of a Vending Machine implementation. Here’s the previous article Finite State Machine with std::variant - C++ Stories States & Events   Here’s a basic diagram that illustrates how the machine is going to work:

In this blog post, I’ll show you how to convert a “regular” enum-style finite state machine into a modern version based on std::variant from C++17. This technique allows you to improve design, work with value types and enhance code quality. States   Let’s start with a basic example: we want to track a game player’s health status we’d like to respond to events like “Hit by a monster” or “Healing bonus.

Last week the ISO committee met in Varna to discuss some of the first batch of C++26 features. It’s an excellent occasion to shed some light on the latest status and interesting C++ proposals. Let’s start! By the way: This will be my first blog post with the #cpp26 tag!

A few years ago (see here, I showed an interesting implementation for self-registering classes in factories. It works, but one step might be at the edge of Undefined behavior. Fortunately, with C++20, its new constinit keyword, we can update the code and ensure it’s super safe. Intro   Let’s bring back the topic:

C++ allows us to declare various forms of non-local objects: they usually live throughout the execution of the whole program. In this article, we’ll look at global variables, dynamic, and thread-local objects. We’ll also consider new features for safe initialization C++20. This text comes from my book “C++ Initialization Story”.

Last time I showed a couple of questions about initialization. Try them here if you haven’t already. In this article, I’ll show you the answers and add more notes about initialization in C++. About   I selected the following questions from 25 questions that you can find in my C++ Initialization Story book:

Do you know the answers to those ten questions about Initialization in Modern C++? About   I selected the following questions from 25 questions that you can find in my C++ Initialization Story book: Print version @Amazon C++ Initialization Story @Leanpub Moreover, in the book, you can find a few coding exercises to practice skills.

I’m thrilled to announce the print/paperback edition of “C++ Initialization Story!” After nearly a year of updates and enhancements for the electronic version, this comprehensive resource is now complete! You can purchase the book in a variety of formats, and to celebrate this major update, I’m hosting a giveaway where you can get the book for free :)

Conceptually a Range is a simple concept: it’s just a pair of two iterators - to the beginning and to the end of a sequence (or a sentinel in some cases). Yet, such an abstraction can radically change the way you write algorithms. In this blog post, I’ll show you a key change that you get with C++20 Ranges.
