The iterator method is available for vector and list on both Linux and Windows platforms.
Erase (iterator _ Where );
However, in Linux, map does not have the iterator erase (iterator _ Where) method );
Therefore, the above Code must be written as mymap in line 26th on Linux. erase (itor ++), but cannot write itor = mymap. erase (itor ). you can use either of the two methods in windows.
