Defined in header <stdexcept>
class out_of_range;

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

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

explicit out_of_range( const std::string& what_arg );
explicit out_of_range( const char* what_arg );
(2) (since C++11)

Constructs the exception object with what_arg as explanatory string that can be accessed through what().

Because copying std::exception is not permitted to throw exceptions, this message is typically stored internally as a copy-on-write string. This is also why there is no constructor taking std::string&&: it would have to copy the content anyway.

[edit] Notes

The standard error condition std::errc::result_out_of_range typically indicates the condition where the result, rather than the input, is out of range, and is more closely related to std::range_error and ERANGE.
