T* data();		（C++11 起）
const T* data() const;		（C++11 起）

返回指针为基础数组作为元素存储。范围[data(); data() + size())始终是一个有效的范围内，即使该容器是空的，该指针是这样.

Original:

Returns pointer to the underlying array serving as element storage. The pointer is such that range [data(); data() + size()) is always a valid range, even if the container is empty.
