The Bridge Pattern – MC++ BLOG
The Bridge Pattern is a structural pattern. It decouples the interface from the implementation. In C++, a simplified version is often used: the Pimpl Idiom. Before I write about the Pimpl Idiom, here are the fact about the Bridge Pattern Purpose Decouples the interface from the implementation Also known as Handle/Body Pimpl (pointer to implementation) Idiom Applicability The interface and the impl
C++20 Concurrency-5: Barrier
In the previous article I discussed about std::latch which is one of the two blocking synchronization primitives introduced in C++20 that can act on multiple threads. The second one being std::barrier . Fundamentally, both needs to be initialized with a counter and can block multiple threads until the counter reaches zero. The only fundamental difference between std::latch and std::barrier is that
Sentinels and Concepts with Ranges Algorithms – MC++ BLOG
You are here: Home1 / Blog2 / C++203 / Sentinels and Concepts with Ranges Algorithms The ranges library in C++20 supports sentinels. Sentinels stand for the end of a range and can be regarded as generalized end iterators. A range provided by a begin iterator and an end sentinel specifies a group of items you can iterate over. The containers of the STL are ranges because their end iterator marks th
Ranges Improvements with C++23 – MC++ BLOG
Thanks to C++23, constructing containers will become more convenient. Additionally, the ranges library got more new views. C++23 is not such a significant standard as C++11 or C++20. It’s more in the tradition of C++17. This is mainly due to COVID-19 because the annual four face-to-face meetings went online. Essentially, the ranges library is the exception to this rule. The ranges will get a few c
50 terrible coding tips for a C++ developer
In case you don't understand why some tip is called terrible, click the {link}. If there is no link, let me know. I'll share a more detailed explanation. A real programmer only programs in C++! {1} If you need a tab character in a string literal, feel free to press the tab key. Save \t ... for somebody else. No worries. Use nested macros everywhere. It's a good way to shorten code. You will free u
C++20 Ranges Algorithms - 11 Modifying Operations
In the previous article in the Ranges series, I covered some basics and non-modifying operations. Today it’s time for algorithms like transform, copy, generate, shuffle, and many more…. and there’s rotate as well :) Let’s go. Before we start Key observations for std::ranges algorithms: Ranges algorithms are defined in the <algorithm> header, while the ranges infrastructure and core types are defin
Check Types with Concepts – MC++ BLOG
Concepts are a powerful and elegant tool to check at compile time if a type fulfills. Thanks to static_assert, you can use concepts as a standalone feature: static_assert(Concept<T>). I often have the question in my C++ class: How can I be sure that my data type is moveable? Well, you can either study the dependencies between the Big Six or define and use the concept Big Six. In my last post, “Che
Bartek's coding blog: Speeding up Pattern Searches with Boyer-Moore Algorithm from C++17
With C++17, you can now use more sophisticated algorithms for pattern searches! You’ll have more control and a promising performance boost for many use cases. This article shows primary usage and runs a benchmark comparing the new techniques. May 2022 Updates: added notes about C++20 and constexpr algorithms, updated the benchmark and compared against std::ranges::search and custom strchr versions
