Optimizing away a “while(1);” in C++0x
...r infinite loops?, although this is WG14 document the rationale applies to C++ as well and the document refers to both WG14 and WG21:
As N1509 correctly points out, the current draft essentially gives
undefined behavior to infinite loops in 6.8.5p6. A major issue for
doing so is that it allo...
Just what is Java EE really? [closed]
...mitigates the risk of vendor lock-in.
It's really no different with C and C++ compilers, where you have many competing offerings as well all adhering to the C++ standard.
Why is Java EE library version not in sync with standard Java library releases (Java EE 6 vs. Java 7)
Java EE builds on Java S...
How exactly does __attribute__((constructor)) work?
...sh them from function calls.
GCC-specific syntax.
Yes, this works in C and C++.
No, the function does not need to be static.
The destructor runs when the shared library is unloaded, typically at program exit.
So, the way the constructors and destructors work is that the shared object file contains...
Skip List vs. Binary Search Tree
... co-author to all three of these winner-algorithm papers. "Algo.27" is the C++ implementation of Fraser's skip list.
Gramoli's conclusion is that's much easier to screw-up a CAS-based concurrent tree implementation than it is to screw up a similar skip list. And based on the figures, it's hard to d...
What are inline namespaces for?
C++11 allows inline namespace s, all members of which are also automatically in the enclosing namespace . I cannot think of any useful application of this -- can somebody please give a brief, succinct example of a situation where an inline namespace is needed and where it is the most idiomatic s...
Is it ever advantageous to use 'goto' in a language that supports loops and functions? If so, why?
...e are sitations where gotos are important: for instance, an exception-less C++ environment. In the Silverlight source we have tens of thousands (or more) of goto statements for safe function exist through the use of macros - key media codecs and libraries often work through return values and never e...
Why is C so fast, and why aren't other languages as fast or faster? [closed]
...n you're an idiot. It just means you are still human. I realize that C and C++ isn't bad (i very much like them).

What is the difference between a strongly typed language and a statically typed language?
...ructors?" In C the answer is no. In CLU, F#, and Haskell it is yes. For C++ I am not sure—I would like to know.
By contrast, static typing means that programs are checked before being executed, and a program might be rejected before it starts. Dynamic typing means that the types of values ar...
Is gcc 4.8 or earlier buggy about regular expressions?
I am trying to use std::regex in a C++11 piece of code, but it appears that the support is a bit buggy. An example:
