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

By Adrien Hamelin | Aug 21, 2015 08:39 AM | Tags: c++11 basics

Here is some reasonning of the new standard:

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...

С++ Hints

By Andrey Karpov | Aug 19, 2015 11:50 PM | Tags: hints c++ basics

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

By Adrien Hamelin | Aug 14, 2015 09:31 AM | Tags: c++11 basics

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

By Adrien Hamelin | Jul 31, 2015 07:53 AM | Tags: c++11 basics

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...

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...

Bitesize Modern C++: nullptr--Glennan Carnie

An article about the null value of a pointer:

Bitesize Modern C++: nullptr

by Glennan Carnie

From the article:

What’s the value of a null pointer?

• 0
• NULL
• NUL

No doubt you’ve been involved in the (always heated) discussions about which is the correct one (By the way, if you said NUL you need to take yourself to one side and give yourself a stern talking to)...

Bitesize Modern C++: enum class--Glennan Carnie

A simple and complete explanation of the enum:

Bitesize Modern C++: enum class

by Glennan Carnie

From the article:

Enumerated types in C++ give a trivial simulation of symbolic types – that is, objects whose instances have unique, human-readable values. In C++ enumerations are essentially named integers that are either assigned values implicitly by the compiler or explicitly by the programmer (or a combination of both)...

The Four Polymorphisms in C++ -- Peteris Krumins

By Niks | Jun 24, 2015 04:39 AM | Tags: basics

C++ has more than one ways to express polymorphism. Discover the nomenclature and read examples on all of them in the following article :

The Four Polymorphisms in C++

by Peteris Krumins

From the article:

(...) These polymorphisms also go by different names in C++ :

• Subtype polymorphism is also known as runtime polymorphism.
• Parametric polymorphism is also known as compile-time polymorphism.
• Ad-hoc polymorphism is also known as overloading.
• Coercion is also known as (implicit or explicit) casting.
