Handling files in C++ - using boost::filesystem
The 9th installment of my series on writing applications in C++ using Qt and boost:
Handling files - using boost::filesystem
by Jens Weller
From the article:
As part of my data is actual files (images, css, js, files...), I realized that the best way to handle those, would be to just store and load them from the file system. In the UI Qt even offers good support for displaying a folder in an Application with QFileSystemModel. But in the application...
Announcing the Meeting C++ Workshop Day!
I finally can announce the Meeting C++ Workshop day on Dec. 3rd in front of the Meeting C++ Conference:
Announcing the Meeting C++ Workshop Day!
by Jens Weller
From the article:
For the first time ever, I do organize a Workshop Day in front of Meeting C++! This is going to be a fun day giving you the knowledge of either C++ in embedded or parallelism.
While some details are still in the making, I already can announce that the speakers of the parallelism workshop are Thomas Heller, Boris Schäling and Michael Wong! The embedded workshop will feature a hands on session from KDAB "Creating HMI for embedded devices with C++ and Qt/QML" by Tobias Koenig.

Bitesize Modern C++ : Range-for loops--Glennan Carnie
Bitesize Modern C++ : Range-for loops
by Glennan Carnie
From the article:
If you’re using container classes in your C++ code (and you probably should be, even if it’s just std::array) then one of the things you’re going to want to do (a lot) is iterate through the container accessing each member in turn.
Without resorting to STL algorithms we could use a for-loop to iterate through the container...
KDAB starts the C++ roadshow across the US in September
KDAB offers his current C++11/14 course, a two day training for just $499:
C++ US Roadshow
by KDAB
Details:
In September, well-known software trainers KDAB, will visit Boston, Chicago, Austin and the Bay Area with a 2 day training class designed for seasoned C++ users on “What’s new in C++11 and C++14?” for just $499 per person.
What’s in it for me?
The importance of C++11/C++14 in the C++ ecosystem is growing fast and inevitably will become the version most used before long. Every professional developer should invest in learning it and introducing its benefits into projects...
Easier To Use, And More Expressive--Tony DaSilva
Easier To Use, And More Expressive
by Tony DaSilva
From the article:
One of the goals for each evolutionary increment in C++ is to decrease the probability of an average programmer from making mistakes by supplanting “old style” features/idioms with new, easier to use, and more expressive alternatives. The following code sample attempts to show an example of this evolution from C++98/03 to C++11 to C++14...
ะก++ Hints
Within the scope of this project, we publish 1 recommendation/tip on C and C++ programming every day, these tips containing concentrated information on techniques of using the C/C++ language in various situations, and including examples of incorrect and correct use from more than 200 open-source projects we have scanned.
C++ Hints
by PVS-Studio Team
From the hint:
Although the code is neat and easy-to-read, it didn't prevent the developers from overlooking the error. You can't stay focused when reading code like that because all you see is just similarly looking blocks and you can't help just quickly scanning through them. These similar blocks have most likely resulted from the programmer's desire to optimize the code as much as possible. He or she just "unrolled the loop" manually. I don't think it was a good idea in this case.
Bitesize Modern C++: std::initializer_list--Glennan Carnie
Do you know how to use initializer lists?
Bitesize Modern C++: std::initializer_list
by Glennan Carnie
From the article:
An aggregate type in C++ is a type that can be initialised with a brace-enclosed list of initialisers. C++ contains three basic aggregate types, inherited from C:
- arrays
- structures
- unions
Since one of the design goals of C++ was to emulate the behaviour of built-in types it seems reasonable that you should be able to initialise user-defined aggregate types (containers, etc.) in the same way...
Bitesize Modern C++: Uniform initialization--Glennan Carnie
Do you know how the uniform initialization?
Bitesize Modern C++: Uniform initialization
by Glennan Carnie
From the article:
C++98 has a frustratingly large number of ways of initialising an object.
(Note: not all these initialisations may be valid at the same time, or at all. We’re interested in the syntax here, not the semantics of the class X)
One of the design goals in C++11 was uniform initialisation syntax...
Bitesize Modern C++: using aliases--Glennan Carnie
Do you know how to use type aliasing?
Bitesize Modern C++: using aliases
by Glennan Carnie
From the article:
In a C++ program it is common to create type aliases using typedef. A type alias is not a new type, simply a new name for an existing declaration. Used carefully, typedef can improve the readability and maintainability of code – particularly when dealing with complex declarations...
