boost::array<char,7> buf = {'a','b','c','d','e','f','g'};
...
...
std::cout << buf.data() + 5;
It’s display: fg
How to understand it?
buf.data() + 5
Thanks
buf.data()seems to return a pointer to the internal array buffer in question.From there, standard pointer arithmetic applies, and you see the 6th character onwards in the
std::cout.operator<<call.
