Does ternary conditional operator bind the order of evaluation?
std::string output( std::string const& r ) { std::string const b( "(" + r + ")" ); std::cout << b << "; "; return b; } template< typename ... ri > nop( ri const& ... r ) {} the order of evaluation of parameters is unspecified, so the following expression: nop( output( output("1") ), output( "2" ) ... 23 Jul 2010 08:03

Any hopes for export ?
Hello As you may know export has been a controversial feature for templates in C++, although also a somewhat promising and a much-awaited one for the more technical programmer, that even to date has hardly received support in compilers. You may hear that much of the controversy started with a paper by Herb Su... 13 Aug 2010 19:03

unordered_map non-existent key
Hi, what happens if I try to access a non-existent key by using operator[] ? e.g. #include <unordered_map> typedef std::unordered_map<int,int> IntHash; typedef IntHash::value_type ValuePair; int main() { IntHash H; H.insert(ValuePair(3,9)); int v = H[7]; cout << v << endl; } gcc-4.4.4 does ... 22 Jul 2010 10:17

Static Analysis Test-Sourcecode ?
Hi all! Do you know of any resource(s) that provide sourcecode to test static analysis tools (such as cppcheck, lint, converity, ...) I'm thinking of a simple program consisting of a few source-files that incorporates all the "errors" of books such as [C++ Coding Standards, Sutter, Alexandrescu] or [C++ Got... 20 Jul 2010 10:13

Is there any standard/guarantees for exception safety in STL operations?
Thomas Richter wrote: ??? How should I know how many resources are available? The lack of any strong guarantee more or less means that proper handling of resource exhaustion is impossible if you insert more than one element at once. IOW, all I can do then is to terminate the program? Now, for *that* I... 1 Aug 2010 19:10
