Stupid std::tuple tricks: Finding a type in a tuple

by Raymond Chen

Given a tuple, you can extract the type of the Nth element in the tuple with the help of std::tuple_element_t<N, Tuple>...

ModernCppStarter & PVS-Studio Static Code Analyzer

by PVS-Studio Team

plog-converter will convert the report into the errorfile format (similar to GCC's messages), which can be conveniently viewed in a terminal window and the IDE. You can also have the report converted to an HTML file by using the -t fullhtml flag. Use the flags -a and -d to filter diagnostics. Run the plog-converter --help command to view the full list of available options.

Stupid std::tuple tricks: Creating more interesting index sequences

by Raymond Chen

Last time, we wrote offset_sequence_t, which takes an existing sequence and adds a fixed value to each element. This is the sort of index manipulation you may want to generalize. So let’s generalize it...

Stupid std::tuple tricks: Creating interesting index sequences

by Raymond Chen

We saw last time that manipulating tuples boils down to the index_sequence. The problem is that the C++ standard library doesn’t provide very much in the way of helpers to manipulate these index sequences...

Stupid std::tuple tricks: Selecting via an index sequence, part 2

by Raymond Chen

Last time, we developed the select_tuple function which takes a tuple and an index sequence and produces a new tuple that selects the elements based on the index sequence...

C++ Template: A Quick UpToDate Look(C++11/14/17/20)

by Vishal Chovatiya

I know, it’s been a while since the last time I published something newbies-friendly on my blog. The main reason is that most of my readers are either experienced devs or from C background having modest C++ encounter. But while programming in C++ you need a completely different mindset as both C & C++ belongs to different programming paradigm. And I always strive to show them a better way of doing things in C++. Anyway, I found the topic which is lengthy, reasonably complex(at least it was for me), newbies-friendly as well as energizing for experienced folks(if Modern C++ jargons, rules & features added) i.e. C++ Template.

I will start with a simple class/function template and as we move along, will increase the complexity. And also cover the advance topics like the variadic template, nested template, CRTP, template vs fold-expression, etc. But, yes! we would not take deeper dive otherwise this would become a book rather than an article.

The C++ Lambda Story Book

by Bartlomiej Filipek

Lambda Expressions appeared in C++11, and since then they become one of the most distinguishing features of Modern C++. What’s more, with each revision of the Standard the ISO Committee improved the syntax and capabilities of lambdas, so they are even more comfortable to use.

Read on to see how you can learn all the details of this powerful modern C++ feature.

by Raymond Chen

Last time, we combined tuples. That’s relatively straightforward. Splitting them apart is harder.

C++ Move Semantics - The Complete Guide

by Nico Josuttis

Having 200 pages, the description of move semantics is feature complete now. Only a few chapters about the use of move semantics in the C++ standard library are missing.

The book teaches all aspects of C++ move semantics. Starting from the basic principles it motivates and explains all features and corner cases (such as perfect returning with decltype(auto)) so that a C++ programmer can understand and use move semantics right in application code, when implementing classes, in generic code, and in foundation libraries.

Transforming C to C++

by Zeb Mason

Performs a clustering analysis on a C call graph then manipulates it within Visual Studio to prototype a class.
