empty()戻りfalse、ポインタが範囲[data(); data() + size())が有効であり、それの値が文字列に格納された値に対応するようになっている場合。 empty()戻りtrue、ポインタが間接参照されない非ヌルポインタである場合。 (C++11以前)

Original:

If empty() returns false, the pointer is such that the range [data(); data() + size()) is valid and the values in it correspond to the values stored in the string. If empty() returns true, the pointer is a non-null pointer that should not be dereferenced. (C++11以前)

ポインタが範囲[data(); data() + size()]が有効であり、それの値がempty()はtrueを返す場合でも、文字列に格納される値（追加のNULL文字を含む）に対応するようなものである。 (C++11およびそれ以降)

Original:

The pointer is such that the range [data(); data() + size()] is valid and the values in it correspond to the values stored in the string (including the additional null character) even when empty() returns true. (C++11およびそれ以降)

data()から得られたポインタは文字列上の任意の非const操作の後に有効と見なされるべきではない.

Original:

The pointer obtained from data() should not be considered valid after any non-const operation on the string.

Original:

Since C++11, data() and c_str() perform the same function.
