How can I distinguish a variable as a compiler-constructed string? For example, while the rvalue \"Hello, World\" is of type const char*. const char* in itself does not mean that a pointer can\'t be[详细]

Being not declared constexpr, std::forward will discard constexpr-ness for any function it forwards arguments to. Why is std::forward not declared constexpr itself so it can preserve constexpr-ness?[详细]

As far as I understand one of the purposes of addingmove semantics is to optimize code by calling special constructor for copying \"temporary\" objects. For example, in this answer we see that it can[详细]

After finding the answer to How to return an fstream (C++0x), I was now wondering if t开发者_运维百科here is a current c++0x library that implements move (or even swap) for fstreams (as gcc (27.9) doe[详细]

I\'m a simple programmer.My class members variables most often consists of POD-types and STL-containers. Because of this I seldom have to write assignment operators or copy constructors, as these are[详细]

Considering the high quality of today\'s compilers regarding return value optimization (both RVO and NRVO), I was wondering at what class complexity it\'s actually meaningful to start adding move cons[详细]
