1Defines a type of object to be thrown as exception. 
2It reports errors that are consequence of attempt to access elements out of
3defined range.

5It may be thrown by the member functions of std::bitset and std::basic_string,
6by std::stoi and std::stod families of functions,
7and by the bounds-checked member access functions
8(e.g. std::vector::at and std::map::at).

1Replace throw std::out_of_range; with throw std::out_of_range ("blah");. I.e. you need to create an object, you cannot throw a type.
