I have something like this: #include <iostream> namespace N { typedef std::pair<int, double> MyPair;
I\'ve been bitten by this problem a couple of times and so have my colleagues. When compiling #include <deque>
Consider this code: template <int N> struct X { friend void f(X *) {} }; int main() { f((X<0> *)0); // Error?
I have two functions : void foo(const char * p) and template<size_t T_Size> void foo(const char (& p)[T_Size]) ;
Some time ago I read an article that explained several pitfalls of argument dependent lookup, but I cannot find it anymore. It was about gaining access to things that you should not have a开发者_如何转
What part of the C++ specification restricts argument dependent lookup from finding function templates in the set of associated namespaces? In other words, why does the last call in main below fail to
Looking at n3092, in §6.5.4 we find the equivalency for a range-based for loop. It then goes on to say what __begin and __end are equal to. It differentiates between arrays and other types, and I fin
How does the C++ compiler decide which function/method to call if there are multiple possibilities? In my specific case I have the standard free function of the C++ Run time and I also have a template
