定义要作为异常引发的对象类型。它报告试图访问定义范围之外的元素所导致的错误。它可以由std：：bitset和std：：basic_string的成员函数、std：：stoi和std：：stod函数族以及边界检查的成员访问函数（例如std：：vector：：at和std：：map：：at）抛出。
继承关系如下：
Member functions
1-2) Constructs the exception object with
what_arg
as explanatory string that can be accessed through
what()
.
3) Copy constructor.
If
*this
and
other
both have dynamic type
std::out_of_range
then
std::
strcmp
(what
(
), other.
what
(
)
)
==
0.
(since C++11)
Parameters
what_arg
explanatory string
Notes
Because copying
std::out_of_range
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.
Assigns the contents of
other
.
If
*this
and
other
both have dynamic type
std::out_of_range
then
std::
strcmp
(what
(
), other.
what
(
)
)
==
0 after assignment.
(since C++11)
Parameters
other
another exception object to assign
