Word Counting in C++: Implementing a Simple Word Counter--Jonathan Boccara

Useful to learn.

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...

JSON for Modern C++ version 3.3.0--Niels Lohmann

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...

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.

CppCon 2017: Web | C++--Lukas Bergdoll

By Adrien Hamelin | Sep 19, 2018 12:57 PM | Tags: community

Have you registered for CppCon 2018 in September? Late registration is open now.

While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2017 for you to enjoy. Here is today’s feature:

Web | C++

by Lukas Bergdoll

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Have you ever tried writing a web application with C++? Can opening a file and serving it via HTTP be as simple as writing 20 lines of python? With the undeniable importance of web development, C++ can not allow itself to ignore such an important field, especially with the rising competition in the field of system programming languages, coming from Rust, D and Go.

Join us as we explore modern approaches to asynchronous IO, socket communication the advantages and disadvantages of using a unikernel and their respective performance implications.

We'll also take a look at how future iterations of the C++ standard library, could solve some of those problems.
