Second Annual C++ Foundation Developer Survey "Lite"

cpp_logo.pngThe Standard C++ Foundation's second annual global C++ developer survey is now open. As the name suggests, it's a one-pager:

2019 Annual C++ Developer Survey "Lite"

Please take 10 minutes or so to participate! A summary of the results, including aggregated highlights of common answers in the write-in responses, will be posted publicly here on isocpp.org and shared with the C++ standardization committee to help inform C++ evolution.

The survey closes in one week.

Thank you for participating and helping to inform our committee and community.

How to Iterate Through Directories in C++

Do you know how to iterate through directories in modern C++? How to work with std::filesystem to solve this task?

How to Iterate Through Directories in C++

by Bartlomiej Filipek

From the article:

How would you implement a function that searches for files with a given extension? For example, finding all text files? or *.cpp files? To code that solution you need a way to iterate through directories. Is that possible in C++ out of the box using the standard library? Let’s see some techniques and new elements that C++17 added.

ACCU - Trip Report

by Ori Ben-Shir

From the article:

I was attending this year ACCU conference, and I am very eager to share my impression of the conference. ACCU is an annual conference located in the lovely city of Bristol. The conference is mostly dedicated to C++ developer. While C++ developers are in mind, the conference is not limited to C++ material, and it includes talks for various topics and even some other programming languages. Yes, there was a Rust talk and even a workshop this year.
It was the first time I have attended a big conference. And I must admit it was a great pleasure! I’m in love with the concept of technical talks. I find it to be the most effective learning method for me. The opportunity to meet a lot of tech enthusiastic is both fun and enriching. Wrapping it all with a vacation for such a lovely city such as Bristol is immensely satisfying. If you have the opportunity, I encourage you to attend this conference next year. I also think the organizers did a great job. I genuinely like the extra social session. The pub quiz, for instance, was perfect, though some of the code samples from it were as far from perfect as possible.

I have a lot to say about the content itself. I tend to believe I have more to say than you want to read. So let’s focus on some of the talks I think are more relevant...

ACCU 2019 trip report

by Mathieu Ropert

From the article:

This year’s edition of ACCU was held from April 10th to April 13th, in Bristol as always. I arrived a day earlier from Paris after a short stop in France which was supposed to offer some supply of good weather and trips to a few winemakers in preparation for the harsh conditions of Great Britain.

From the start things went awry as I could only spare half an hour for a visit to a winemaker in Vouvray who turned out to be quite forgettable, not to mention the weather that was only barely keeping it up together. Still I didn’t immediately notice that something was off, having spent the pasts months enduring the cold winter of Sweden. It took a second flight from Paris to Bristol to realize it: spring is there (although a couple of Bristol locals apologized for the weather being unexpectedly non-terrible)...

Quick Q: Does the default constructor initialize built-in types?

Quick A: No.

Recently on SO:

Does the default constructor initialize built-in types?

Implicitly defined (by the compiler) default constructor of a class does not initialize members of built-in types.

However, you have to keep in mind that in some cases the initialization of a instance of the class can be performed by other means. Not by default constructor, nor by constructor at all...

New speakers are welcome to submit as there is a dedicated track for this, start speaking at Meeting C++!

Submit your talk to Meeting C++ 2019!

by Jens Weller

From the article:

When Meeting C++ 2019 was announced in the begin of April, there was already a hint that you could submit your talks. And so far a few have done so. Now its time for an official news entry. Submit your talk to Meeting C++ 2019! This year its the 8th edition of Meeting C++!

Speaking at Meeting C++ is a fun experience, you get to attend the speakers dinner, attend the full conference for free and enjoy the luxurious Hotelrooms the Andels offers from Wednesday to Saturday! You can look at last years schedule to get a feel for what your competition might talk about, but have in mind that you don't see the talks that were not submitted! If you want to talk about a C++ topic that wasn't covered yet, or have a unique idea for your talk, please submit! Speakers don't need to buy a ticket and the conference has a contingent of rooms available for speakers & staff.
