Defined in header
Defines a type of object to be thrown as exception. It can be used to report range errors (that is, situations where a result of a computation cannot be represented by the destination type)
The mathematical functions in the standard library components do not throw this exception (mathematical functions report range errors as specified in math_errhandling).
 Member functions
| constructs the exception object |
(public member function)
explicit range_error( const std::string& what_arg );
explicit range_error( const char* what_arg );
Constructs the exception object with
what_arg as explanatory string that can be accessed through what().
std::exception is not permitted to throw exceptions, this message is typically stored internally as a separately-allocated reference-counted string. This is also why there is no constructor taking
std::string&&: it would have to copy the content anyway.
May throw std::bad_alloc
