顺便说一句,我仍然不相信这比编写transform_if更好。使用Niebler的range v3,应该可以编写类似于std::vector<int> arrKeys = theMap | view :: remove_if([&](auto const& p){return p.second!= value; })| view :: keys;的代码(未经测试) - dyp...

for (auto& el : obj) el.~std::remove_extent_t<T>(); 或 std::destroy_at(std::addressof(obj));)。 但是,对于 std::unordered_map, value_type 是 std::pair<const key_type, mapped_type>。这种类型是可破坏的,只是很难构造。 你不能像 std::pair<const int, int[2]>{ 1, temp }那...
