Question

What are the common misuse of using STL containers with iterators?

Answer 1

Forgetting that iterators are quite often invalidated if you change the container by inserting or erasing container members.

For many great tips on using STL I highly recommend Scott Meyers's book "Effective STL" (sanitised Amazon link)

Answer 2

The end range check should be using != and not < since the order of the pointers isn't guaranteed.

Example:

for(it = list.begin(); it != list.end(); ++it)
{
     // do stuff
}
