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 复制 // map_insert.cpp // compile with: /EHsc #include <map> #include <iostream> int main( ...
For insertion of an element constructed in place—that is, no copy or move operations are performed—see map::emplace and map::emplace_hint. Example c++ Copy // map_insert.cpp // compile with: /EHsc #include <map> #include <iostream> #include <string> #include <vector> #include <uti...
