Linux与Windows中map类erase方法的差异

1 #include < iostream > 2 #include < map > 3 #include < string > 4 5 using namespace    std; 6 7 int main( int argc, char * argv[]) 8 { 9      map < string , int > MyMap; 10 11      MyMap[ " bujiwu " ] = 26 ; 12      MyMap[ " swallow " ] = 25 ; 13 14      std::cout << " Before delete element: " << std::endl; 15      for ( map < string , int > ::iterator Itor = MyMap.begin(); 16              Itor != MyMap.end(); Itor ++ ) 17      { 18          std::cout << Itor -> first << "     " << Itor -> second << std::endl; 19      } 20 21      for ( map < string , int > ::iterator Itor = MyMap.begin(); 22              Itor != MyMap.end(); ) 23      { 24          if ( Itor -> first == " bujiwu " ) 25          { 26              MyMap.erase(Itor ++ ); //在windows下也可以Itor = MyMap.erase(Itor),但是在linux下不行。 27          } 28          else 29          { 30              Itor ++ ; 31          } 32      } 33 34      std::cout << " After delete element: " << std::endl; 35      for ( map < string , int > ::iterator Itor = MyMap.begin(); 36              Itor != MyMap.end(); Itor ++ ) 37      { 38          std::cout << Itor -> first << "     " << Itor -> second << std::endl; 39      } 40 41      return 0 ; 42 } 43 44

通过测试在不管在linux还是Windows平台下,vector,list都有方法iterator erase( iterator _Where ); 但是在Linux下map中没有方法iterator erase( iterator _Where ); 所以上述代码在Linux平台下第26行必须写成MyMap.erase(Itor++),而不能写能Itor = MyMap.erase(Itor). 在Windows下二种方法都可以。
