Pros and Cons of Alternative Function Syntax in C++—Petr Zemek

Do you know the trailing return type?

Pros and Cons of Alternative Function Syntax in C++

by Petr Zemek

From the article:

C++11 introduced an alternative syntax for writing function declarations. Instead of putting the return type before the name of the function (e.g. int func()), the new syntax allows us to write it after the parameters (e.g. auto func() -> int). This leads to a couple of questions: Why was such an alternative syntax added? Is it meant to be a replacement for the original syntax? To help you with these questions, the present blog post tries to summarize the advantages and disadvantages of this newly added syntax...

Return early and clearly—Arne Mertz

How to return well:

Return early and clearly

by Arne Mertz

From the article:

There are different guidelines out there about where and how many return statements to use in a function, e.g. return only once at the end of the function or return early and often. Which one makes for the most readable code?

Simplifying templates and #ifdefs with if constexpr—Simon Brand

The new if constexpr will change a good part of our code for the better!

Simplifying templates and #ifdefs with if constexpr

by Simon Brand

From the article:

if constexpr is a C++17 feature which allows conditionally compiling code based on template parameters in a clear and minimal fashion. It is essentially an if statement where the branch is chosen at compile-time, and any not-taken branches are discarded without being instantiated...

C++ 17 Transformation…—phantom

The transformation is only a beginning towards catching up from C++98, but it does show why modern C++ features improve your code.

C++ 17 Transformation...

by phantom

From the article:

I'm basically really bad at working on my own projects, but with the recent release of Visual Studio 2017 RC and its improved C++17 support I figured it was time to crack on again...

To that end I've spent a bit of time today updating my own basic windowing library to use C++17 features. Some of the things have been simple transforms such as converting 'typedef' to 'using', others have been more OCD satisfying...

Basic dependent typing—Krzysztof Ostrowski

Using fundamental types to do "simple things simple" fits very well in the most of cases.

Basic dependent typing

by Krzysztof Ostrowski

From the article:

If we assume that our application uses only a subset of values carried by given fundamental type, we are likely to get warning from the compiler. We shall take that warning seriously. How to inform type system about our assumptions? Example solutions follow.
