## iterator.txt
As we are not experts on STL iterators, Never ever modify (insert or remove something) in a data structure when you are traversing a STL container (with iterators). YOU DONT WANT TO WASTE TIME DEBUGGING
We don't want to go into the implementation details about invalidating iterators of various containers in different standards of C++ (03, 11 and more in future)

To just give you a rough idea, to simply put it... as a beginner, let us just remember as - 'Iterator of the modified STL container becomes invalidated - means it becomes invalid, erroneous'.

Actually, it doesn't occur in all cases of modification.
To be more technical and precise :

As per the standard : for STL set
The insert members shall not affect the validity of iterators and references to the container, and the erase members shall invalidate only iterators and references to the erased elements.
