Word Counting in C++: Implementing a Simple Word Counter

by Jonathan Boccara

From the article:

Word counts can reveal information about your code, or make an unknown piece of code more expressive to your eyes.

There are online tools to count words in generic text, but most of those I’ve come across are designed around counting words in text and SEO (Search Engine Optimization). Since analysing source code is not the same thing as analysing the text of a blog post, let’s design a tool fit for our needs of counting words in code. This way, we will be able to make it evolve when we discover new tasks to try with our word counter.

Another reason to write our own word counter is that it will let us practice interface design, and also STL algorithms, which are useful to master for coding in C++.

For this first version of our word counter, the objective will be to put together a working prototype. Then we will improve it over future posts, by adding features and by refining its implementation...

The next episode of the 'most useful C++ links' is now available:

C++ Links #6

by Bartlomiej Filipek and Wojciech Razik

From the article:

Welcome to new C++ Links - most important and useful articles, podcasts and videos that happen between 6th and 12th of October.

Today you will find a link to Core Guidelines rules about Concepts, a long article about C++17 class template deduction and a video that shows how inline keyword is taken into account by the compiler. At the end, you will also find a bonus!

New Pluralsight Course: Introduction to Data Structures and Algorithms in C++—Giovanni Dicanio

By Giovanni Dicanio | Oct 9, 2018 09:53 AM | Tags: None

A new course was published in the Pluralsight library:

Introduction to Data Structures and Algorithms in C++

by Giovanni Dicanio

From the article:

In this course, you’ll learn how to implement some fundamental data structures and algorithms in C++ from scratch, with a combination of theoretical introduction using slides, and practical C++ implementation code.

No prior data structure or algorithm theory knowledge is required. You only need a basic knowledge of C++ language features.

Are you using it?

JSON for Modern C++ version 3.3.0

by Niels Lohmann

From the article:

This release adds support for GCC 4.8. Furthermore, it adds a function get_to to write a JSON value to a passed reference. Another topic of this release was the CMake support which has been overworked and documented.

Besides, a lot of bugs have been fixed and slight improvements have been made. All changes are backward-compatible...

std::any: How, when, and why—Casey Carter

std::any: How, when, and why

by Casey Carter

From the article:

C++17 adds several new “vocabulary types” – types intended to be used in the interfaces between components from different sources – to the standard library. MSVC has been shipping implementations of std::optional, std::any, and std::variantsince the Visual Studio 2017 release, but we haven’t provided any guidelines on how and when these vocabulary types should be used. This article on std::any is the second of a series that examines each of the vocabulary types in turn...

“auto to stick” and Changing Your Style—Jonathan Boccara

“auto to stick” and Changing Your Style

by Jonathan Boccara

From the article:

While performing a code review on a refactoring project, I stumbled upon a change that took a line of code from this state:

Widget myWidget{42};

to that:

auto myWidget = Widget{42};

Well, in the actual case the type wasn’t called Widget and the initialization value wasn’t exactly 42. But that’s the gist of it...

ACCU 2019 Call for Papers—ACCU

By Felix Petriconi | Oct 7, 2018 11:19 AM | Tags: community

The ACCU 2019 is now putting together its program, and they want you to speak on C++. The ACCU has a strong C++ track, though it is not a C++-only conference. If you have something to share, check out their

Call for Papers

by the ACCU

From the article:

Historically, ACCU has a lot of C++ and C content, and is proud of that: ACCU is the foremost annual conference for people interested in C++ and C, at least in and around the UK. But it is not just a C++ and C conference, ACCU is about programming in whatever language people are using, with whatever tools and processes people are using: D, Chapel, Java, Kotlin, C#, F#, Groovy, Rust, Go, Python, Ruby, Lisp, to name just a few programming languages about which there have been sessions at ACCU conferences. Git, Mercurial, CMake, Meson, TDD, BDD, allthese tools and techniques have been the focus of sessions at ACCU. The ACCU Conference is looking for sessions that will be interesting to people who create software.

The keynote speakers are M. Angela Sasse, Kate Gregory, Paul Grenyer and Herb Sutter.

The Call for Papers lasts for about 3 weeks and will close on Friday 2018-10-26T23:59+01:00.
