For the cover of the first edition of Effective C++, I envisioned Alexander the Great cutting the Gordian Knot. I'm getting ready to start work on Effective C++11 (about which I'll have more to say in a later blog post), and this week I've been reviewing a manuscript for a new book in my Effective Software Development Series, so recently I've been thinking a lot about what makes an effective Effec

The latest reviewed version was checked on 8 September 2023. There are template/file changes awaiting review. C++ has indeed become too "expert friendly" -- Bjarne Stroustrup, The Problem with Programming, Technology Review, Nov 2006. Stroustrup's saying is true because experts are intimately familiar with the idioms in the language. With the increase in the idioms a programmer understands, the la

Many people think of C++ as the same language they experienced in college or just as “C with classes”, but the C++ language has evolved extensively over the years. In this session, we’ll cover how you can use C++ to write innovative, expressive and beautiful apps that deliver power and performance apps. Join us to see how the newly finished C++0x standard can make writing C++ as productive as many

Programming is hard. Programming correct C and C++ is particularly hard. Indeed, both in C and certainly in C++, it is uncommon to see a screenful containing only well defined and conforming code.Why do professional programmers write code like this? Because most programmers do not have a deep understanding of the language they are using.While they sometimes know that certain things are undefined o

C++ Concurrency in Action 著者：Anthony Williams Boost Thread Library作者であるAnthony WilliamsによるC++11の並行プログラミングに関する本。 C++11のスレッドライブラリはBoost.Threadの経験をもとに取り入れられ、Anthony自身も大きく関わっている。 Overview of the New C++ (C++0x) 著者：Scott Meyers Effective C++作者であるScott MeyersによるC++11(旧名C++0x)の概要を書いた本。 未読。 Professional C++ 著者：Marc Gregoire, Nicholas A.

C++03 と C++11 ってどれぐらい互換性があるのかなーと気になっていたんだけど、仕様書の §C.2 を見てみたらずばりなものが載っていたので、一通り読んでみた。 C++03 のコードを C++11 として動かそうとしたときにコンパイルエラーやランタイムエラーが発生したら、これを確認してみるといいかも。 新しい文字列リテラル R, u8, u8R, u, uR, U, UR, LR という新しい文字列リテラルが追加されたため、文字列と一緒にこれらのマクロを使った場合、互換性の無いコードになる可能性がある。 例えば以下のコードは互換性の無いコードである。 #define u8 "abc" const char* s = u8"def"; // C++03 なら "abcdef"、C++11 なら "def" になる ユーザはこの手の短いマクロをよく使うため、この問題はよく発生しそうに見

C++ and Beyond is a small, conference-like event built around intensive technical sessions by Scott Meyers, Herb Sutter, and Andrei Alexandrescu, but designed also to facilitate the exchange of experiences and insights among the unusually talented developers who attend. Technical sessions focus on topics of special interest to professional developers where Andrei, Herb, and Scott have expertise. T

First, a word of warning: This is not portable. Secondly… being able to produce stack traces (outside of the debugger) is something that’s usually reserved for languages like Python or Java… but it’s quite nice to have them in C++. There’s several hurdles to overcome, however. Acquire Stack This part is pretty easy, but unless you’re nosy with the header files in /usr/include, it’s not likely to s
