The third member function inserts the sequence of element values into a map corresponding to each element addressed by an iterator of in the range[_First, _Last)of a specified set. Example Copy // map_insert.cpp // compile with: /EHsc #include <map> #include <iostream> #include <string...
set.insert({2, -1, 9}); // {0} {1} {2} {9} {-1} for(const auto& key : set) { std::cout << "{" << key << "}" << std::endl; } } 异构查找 异构重载允许使用除 Key 之外的其他类型进行查找和擦除操作,只要所使用的类型是可散列的并且与 Key 具有可比性。
