正确版本：

1 #include < iostream >
2 #include < list >
3 #include < algorithm >
4 using namespace   std;
5
6 int main( int argc, char * argv[])
7 {
8     list < int > MyList;
9
10      for ( int i = 0 ; i < 10 ; i ++ )
11     {
12         MyList.push_back(i);
13     }
14
15     list < int > ::iterator Itor;
16
17      for ( Itor = MyList.begin(); Itor != MyList.end(); )
18     {
19          if ( * Itor == 4 )
20         {
21             Itor = MyList.erase(Itor);
22         }
23          else
24         {
25             Itor ++ ;
26         }
27     }
28
29     copy(MyList.begin(), MyList.end(), ostream_iterator < int > (cout, " " ) );
30     cout << endl;
31
32      return 0 ;
33 }

错误版本：

1 #include < iostream >
2 #include < list >
3 #include < algorithm >
4 using namespace   std;
5
6 int main( int argc, char * argv[])
7 {
8     list < int > MyList;
9
10      for ( int i = 0 ; i < 10 ; i ++ )
11     {
12         MyList.push_back(i);
13     }
14
15     list < int > ::iterator Itor;
16
17      for ( Itor = MyList.begin(); Itor != MyList.end(); Itor ++ )
18     {
19          if ( * Itor == 4 )
20         {
21             MyList.erase(Itor); //断链，出错地方
22         }
23     }
24
25     copy(MyList.begin(), MyList.end(), ostream_iterator < int > (cout, " " ) );
26     cout << endl;
27
28      return 0 ;
29 }
