For example, I want to use code like this:
std::vector<int> vec = {1, 2, 3, 4};
std::cout << vec;
Is there a way, to overload << operator?

1If you want to use `<<` then see [this answer](http://stackoverflow.com/a/23397700/4342498) on the dupe target – NathanOliver Jun 06 '16 at 12:24

1Sure, it should look like `std::ostream& operator<<(std::ostream&, const std::vector
)`. – πάντα ῥεῖ Jun 06 '16 at 12:24 -
@NathanOliver, I observe that you are pretty much nailing the dupes. Why don't you help closing it, being a gold badge owner yourself. :-) – iammilind Jun 06 '16 at 12:28

@iammilind I tried but it was closed by Cory 16 seconds before I tried to close it. That last one you closed I didn't because I wasn't 100% sure what the OP wanted. – NathanOliver Jun 06 '16 at 12:31

@LightnessRacesinOrbit Oops, I missed the third `&`. – πάντα ῥεῖ Jun 06 '16 at 12:58
