How to automatically generate a stacktrace when my program crashes
I am working on Linux with the GCC compiler. When my C++ program crashes I would like it to automatically generate a stacktrace.

当一个纯虚函数被调用到时，vc++的debug模式下会弹出这么一个对话框：

Superiority of unnamed namespace over static?
...
You're basically referring to the section §7.3.1.1/2 from the C++03 Standard,
The use of the static keyword is
deprecated when declaring objects in a
namespace scope; the
unnamed-namespace provides a superior
alternative.
Note that this paragraph was already removed in C++...
Calling Python in Java?
...s why python is so kool! Having such high abstractions however access to c,c++ when needed. Imagine if you could have that in java. This question is not even worth asking if jython is ok because then it is easy anyway.
So I have played with the following methods, and listed them from easy to difficu...
Why do you program in assembly? [closed]
..., many modern 3-D Games have their high performance core engine written in C++ and Assembly.
Games (and most programs these days) aren't "written in assembly" the same way they're "written in C++". That blog isn't saying that a significant fraction of the game is designed in assembly, or that a t...
Why are Standard iterator ranges [begin, end) instead of [begin, end]?
...n; it <= end; ++it) { ... }
Since pointers to arrays are iterators in C++ (and the syntax was designed to allow this), it's much easier to call std::find(array, array + size, some_value) than it is to call std::find(array, array + size - 1, some_value).
Plus, if you work with half-closed ran...
Why aren't superclass __init__ methods automatically invoked?
... a default state including its final runtime type. It is not equivalent to C++ constructors, that are called on a statically typed, allocated object with an undefined state. These are also different from __new__, so we really have at least four different kinds of allocation/construction/initializati...

When is it right for a constructor to throw an exception?
...uses two-stage construction because when it was originally written, Visual C++ didn't have C++ exceptions working. Windows CE didn't get C++ exceptions until v4.0, and MFC 8.0.

What are important languages to learn to understand different approaches and concepts? [closed]
...'s a lot of C code lying around---it's definitely practical. If you learn C++ too, there's a big lot of more code around (and the leap is short once you know C and Java).
It also gives you (or forces you to have) a great understanding of some theoretical issues; for instance, each running program ...
