Why doesn\'t this compile: Could there be a problem with a string as a return type? constexpr开发者_开发问答 std::string fnc()
Here is a piece of code: class Class { static constexpr int getBug(); }; constexpr int Class::getBug() { return 0;
std::piecewise_construct, defined in <utility>, has internal linkage since it is declared constexpr. I wonder if use of std::piecewise_construct in a header can violate ODR. For example:
When reading the slides about constexpr the introduction is about \"surprisingly dynamic initialization with consts\". The example is
I noticed, that in [24.4.7] of the last C++-Std Doc N3291 max ist not constexpr: template<class T> const T& max(const T& a, const T& b);
I\'m using gcc 4.6.1 and am getting some interesting behavior involving calling a constexpr function. This program runs just fine and straight away prints out 12200160415121876738.
I couldn\'t find the answer through searching, so next step is asking. Say I have some code like this:
I tried to write a function, which returns an integer with only the highest bit of the input set, using a C++0x constexpr.
I tried to find a solution for the problem of the question C++ template non-type parameter type deduction, which does not involve a template parameter to call f, but implicitly chooses the correct typ
