コンテナが原因でシステムやライブラリの実装上の制限に保持することができる要素の最大数を返し、すなわちstd::distance(begin(), end())最大のコンテナ用の.
Original:
Returns the maximum number of elements the container is able to hold due to system or library implementation limitations, i.e. std::distance(begin(), end()) for the largest container.

[編集] ノート

この値は、通常std::numeric_limits<size_type>::max()に等しく、コンテナのサイズに理論上の制限を反映している。実行時には、容器の大きさは、使用可能なRAMの量によってmax_size()よりも小さい値に制限されるかもしれません.
Original:
This value is typically equal to std::numeric_limits<size_type>::max(), and reflects the theoretical limit on the size of the container. At runtime, the size of the container may be limited to a value smaller than max_size() by the amount of RAM available.
