C Smart Pointers Reference Card Updated: 27 September 2021 Smart pointers available since C++11 are an essential foundation for writing secure code in Modern C++. Thanks to RAII (Resource Acquisition Is Initialization), they allow you to work with pointers to allocate memory or other managed objects efficiently.This blog post will show you the core points for working with those handy types. READ MORE... C Return: std::any, std::optional, or std::variant? Updated: 20 September 2021 What should happen when the data returned from a function is not valid? It might be an error or just how the system operates (embedded environment, a timeout).

C 20 Oxymoron: constexpr virtual Updated: 13 September 2021 Two keywords, constexpr and virtual - can those two work together? Virtual implies runtime polymorphism, while constexpr suggests constant expression evaluation. It looks like we have a contradiction, does it?Read on and see why those conflicting terms might help us get simpler code.A basic example Imagine that you work with some product list, and you want to check if a product fits in a given box size: READ MORE... constexpr vector and string in C 20 and One Big Limitation Updated: 30 August 2021 constexpr started small in C++11 but then, with each Standard revision, improved considerably. In C++20, we can say that there s a culmination point as you can even use std::vector and std::string in constant expressions!Let s look at use cases, required features to make it work, and finally, one significant limitation that we might want to solve in the future. READ MORE... Empty Base Class Optimisation, no_unique_address and unique_ptr Updated: 23 August 2021 C++20 added a couple of new attributes in the form of [[attrib_name]]. One of them - [[no_unique_address]] - can have surprising effects on the code! In this blog post, you ll learn how to optimize your classes' layout and make some data members disappear . In most cases, it will be just one line of C++20 code. READ MORE... Stricter Expression Evaluation Order in C 17 Updated: 16 August 2021 C++ has many dark corners and many caveats that can cause you to scratch your head in confusion. One of the issues we had until C++17 was the evaluation order of expressions. In this blog post, I ll show you the new rules that we got in C++17 that made this complicated term much simpler and practical. READ MORE... How to Parallelise CSV Reader - C 17 in Practice Updated: 09 August 2021 At C++Stories (and in my C++17 book) you can find several articles on Parallel Algorithms introduced in C++17. The examples included in those posts were usually relatively straightforward. How about writing something larger?In this text, you ll see how to build a tool that works on CSV files, parses lines into sales records and then performs calculations on the data. READ MORE... C Lambda Story in Spanish!

READ MORE... Software Architecture with C , Book Review Updated: 19 July 2021 In April, we got a new book - from two Polish authors - Piotr and Adrian - on C++ Software Architecture. This one is fascinating and refreshing. While it won t teach you all the latest C++ features or low-level tricks in our favorite language, it will move you to a higher level with architecture, building, patterns, design, and development for the cloud. READ MORE... Five Awesome C Papers for the Q2 2021 and C 23 Status Updated: 12 July 2021 The work on C++23 continues!
