c++ - What will happen if I keep incrementing an iterator? -


I have a simple question: What if I continue to extend the interferral Iterator () the last one) + STL container? E.g. 

  set & lt; Int & gt; intSet; IntSet.insert (0); IntSet.insert (1); IntSet.insert (2); Set & lt; Int & gt; :: Iterator Setter = intSet.begin (); For (Int i = 0; I & lt; 10; i ++) Set Ether ++;   
 So, will be set intSet.end () always? Or is it an undefined behavior (can I give incompatible junk)?  
  
 
 
 The only work to grow is  nothing , at least the GNU compilers .  
 If you try dereference, it invites undefined behavior.  
 For more discussion, see.
