std::vector::data

STD：：向量：：数据

T* data(​(since C++11)
const T* data() const;​(since C++11)

返回指向作为元素存储的基础数组的指针。指针就是这样的范围。[data( data() + size())始终是有效范围，即使容器为空%28data()在这种情况下%29是不可取消的。

参数

%280%29

返回值

指向基础元素存储的指针。对于非空容器，请返回&front()...

复杂性

常量。

例外

noexcept规格：

noexcept

另见

frontaccess the first element (public member function)
backaccess the last element (public member function)
