推荐答案
由于一个常见的误解,你可能会认为C ++标准库是STL,或者你的工具链中的部分C ++标准库实现为一个STL实现。它不是。
Due to a common misconception, you may think of the C++ Standard Library as "the STL", or of parts of your toolchains implementation of the C++ Standard Library as "an STL implementation". It is not.
这也是一个很大的耻ame,MSVC ++和GCC(其实现 hash_map
作为编译器特定扩展),将其放置在 std
命名空间< a>,这是高度误导。 * sigh *
It is also a great shame that both MSVC++ and GCC (which implement hash_map
as a compiler-specific extension), place it in the std
namespace, which is highly misleading. *sigh*
C ++ 11引入了 std :: unordered_map
,这不是不相似的。
C++11 has introduced std::unordered_map
, which is not dissimilar.
