Defined in header <stdexcept>
class range_error;

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 only standard library components that throw this exception are std::wstring_convert::from_bytes and std::wstring_convert::to_bytes.

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

(constructor)

constructs the exception object (public member function)

std::range_error::range_error

explicit range_error( const std::string& what_arg );	(1)
explicit range_error( 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 separately-allocated reference-counted string. This is also why there is no constructor taking std::string&&: it would have to copy the content anyway.

Member functions

(destructor) [virtual]	destructs the exception object (virtual public member function of std::exception)
what [virtual]	returns an explanatory string (virtual public member function of std::exception)
