| Doug Mika <dougmmika@gmail.com>: Sep 08 07:19AM -0700 Hi to all. I know that ^ is the bitwise XOR operator, but what does it mean in the following: String^ strSource = "changed"; //what is this ^ doing here? Thanks PS. It's taken from: https://msdn.microsoft.com/en-us/library/system.string.copyto(v=vs.110).aspx?cs-save-lang=1&cs-lang=cpp#code-snippet-2 |

That's a Microsoft specific Common Language Runtime specifier meaning the declared object is to be automatically garbage collected. This is not part of standard C++. You should find a microsoft specific newsgroup to find out more. Daniel |

Does anyone know the precise address of the microsoft visual c++ newsgroup? (ie comp.lang.c++) Microsoft has decided that we don't want to use newsgroups anymore - old technology! So the have set up some modern online forums instead. Bo Persson |

Good luck finding one where any specific question is on topic and will receive a response by anyone other than a moderator whom will mark his own post as the answer even though your question never got addressed. -- I have chosen to troll filter/ignore all subthreads containing the words: "Rick C. Hodgins", "Flibble", and "Islam" So, I won't be able to see or respond to any such messages --- |

I.e. making the element inside the pair a constant reference too (`int` doesn't matter in this case because it's a builtin type) because why make a copy of the string if all you're doing is looking at the pair. Something like that? Assuming the above is correct, would `const ::std::pair<::std::string&, int>&` make sense/be valid (i.e. a normal reference to the string inside the pair but a constant reference to the whole pair)? I assume it wouldn't? auxo |
