std::initializer_list::begin

STD：：初始化器[医]清单：：开始

const T* begin() const;​(since C++11) (until C++14)
constexpr const T* begin() const;​(since C++14)

返回指向初始化程序列表中的第一个元素的指针。

如果初始化程序列表为空，则begin()和end()没有具体说明，但将是相同的。

参数

%280%29

返回值

指向初始化程序列表中的第一个元素的指针。

例外

noexcept规格：

noexcept

复杂性

常量。

另见

endreturns a pointer to one past the last element (public member function)
