Template Specialization
by Rainer Grimm
From the article:
Templates define the behavior of families of classes or functions. Often it is required that special types or non-types may be treated special. To support this use case, you can specialize templates.

C++20 three-way comparison operator: Part 2
by Gajendra Gulgulia
From the article:
In the first part of the tutorial series, I laid out the motivation behind C++20’s three way comparison operator: <=> and showcased the simplest use case how it can be useful to remove the boilerplate code for comparison operators : ==, >=, <=, !=, >, < if the semantics of the program requires us to implement them and how they can be gotten rid of by using the defaulted version of three way comparison operator...

To fully test the plugin, you'll need to install both the beta plugin version and the C++ core beta version of the analyzer. There are several ways to install the plugin: from the official repository, from the repository on our site, or using Windows PVS-Studio installer. Below we'll tell you in detail how to do this.
Beta-Testing of PVS-Studio Plugin for JetBrains CLion
by Evgeniy Ovsyannikov, Paul Eremeev
From the article:
We usually recommend running full analysis regularly, such as once a day, at night. In addition to nightly analysis, we highly recommend checking new code immediately after writing it. This way you'll get the best advantage of using the analyzer. To do this, use incremental analysis, which works as follows. A project was changed, a developer runs a build. After successful compilation only modified files will be analyzed. Modified files are the ones that have been changed since the previous analysis.

Template Argument Deduction of Class Templates
by Rainer Grimm
From the article:
In my last post Template Arguments, I wrote about function template type deduction (C++98) and auto type deduction (C++11). Today I wear more modern hats. I start with automatic type deduction of non-type template parameters and class templates (C++17) and finish with automatic type deduction of concepts (C++20).

C++ 17 Class Templates: CTAD and Type Deduction Guide
by Gajendra Gulgulia
From the article:
This article aims to demonstrate the CTAD feature and how to force C++ to deduce type specifically for class templates with the explicit type deduction guides available since C++17.

Reversing words of a string with ranges
by Marco Arena
From the article:
In this post I share the story of a “C++ aha-moment”, hence I use the hashtag #thatsarotate (resumed last Saturday at the Italian C++ Conference 2021 to honor our keynote speaker Sean Parent). Why not sharing your own stories of “C++ aha-moments” adding the same hashtag to your tweets, posts, or whatever? It would be really appreciated...

In this guest blog post, Greg will share a few top tips for debugging C++ code.
7 Top Tips for Debugging C++
by Greg Law
From the article:
Debugging is central to programming – you cannot be a great programmer without being great at debugging. Hopefully, my favorite C++ debugging tips will help you be as clever and productive debugging your code as you are writing it in the first place.
- #1 Have a full kit of debugging tools
- #2 Conditional breakpoints
- #3 Watchpoints
- #4 User-defined debugging commands in Python
- #5 Pretty-print structures
- #6 Time Travel Debugging
- #7 Command find to search for a byte sequence

Another twist on ranges.
Transrangers: An Efficient, Composable Design Pattern for Range Processing
by Joaquín M López Muñoz
From the article:
Transrangers are a new design pattern for efficient, composable range processing that can be faster than pull-based C++/Range-v3 views whithout losing any expressiveness. The underlying architecture combines ideas from push processing with the internalization of control flow. Transrangers can be used on their own or be leveraged as an implementation detail of range libraries to improve the performance of view-based operations.
