[RESOLVED] Extracting Elements from STL maps

I have a giant map and using iterator and lower_bound functions I have been able to narrow down to a range relevant to me.

Now I want to copy the locations from first_iterator to last_iterator to another map or rather create a new map from first_iterator to last_iterator. Is there an automatic way of doing it instead of me writing a for loop?

Thanks guys

Use the insert member function that takes 2 iterators:

Code:

---

m2.insert(it_lower,it_upper);

---

where

it_lower is the lower bound iterator
it_upper is the upper bound iterator
m2 is the map you want to insert into
