Just As Fast, But Easier To Write

I love watching Herb Sutter videos on C++. His passion and enthusiasm for the language is infectious. Like Scott Meyers, Herb always explains the “why” and “how” of a language feature in addition to the academically dry “what” .

In this talk, “Writing modern C++ code: how C++ has evolved over the years“,  Herb exhibits several side by side code snippets that clearly show much easier it is to write code in C++11 (relative to C++98) without sacrificing efficiency.

Here’s an example (which I hope isn’t too blurry) in which the C++11 code is shorter and obsoletes the need for writing an infamous”new/delete” pair.

Note how Herb uses the new auto, std::make_shared, std::shared_ptr, and anonymous lambda function features of C++11 to shorten the code and minimize the chance of making mistakes. In addition, Herb’s benchmarking tests showed that the C++11 code is actually faster than the C++98 equivalent. I don’t know about you, but I think this is pretty w00t!

I love paradoxes because they twist the logical mind into submission to the cosmos. Thus, I’m gonna leave you with this applicable quote (snipped from Herb’s presentation) by C++ expert and D language co-creator Andrei Alexandrescu:

Note: As a side bonus of watching the video, I found out that the Microsoft Parallel Patterns Library is now available for Linux (via Intel).

    So glad I’ve clung to C++ over the years, and ignored those who kept chittering about Java and C# and how great they are because “it has garbage collection”. They remind me of the future Americans in “Idiocracy” – it’s what plants want! Why? It’s got electrolytes! So? It’s what plants want!

      I’m obviously biased, but compared to BD00, I think C++ has a bright future. 🙂
