Question

These iterator in the collection classes confuses me. I got a Map with key of string, and value being a Vector class (similar to an array). As i understand it my iterator variable it is assigned to the map. So i should be able to to get it´s value and assign it to a new Vector class so I can read it´s contents or know it´s size etc… but how do I do this?

for (Map<string, Vector<string> > :: iterator it = array0.begin();
                                         it != array0.end(); it++)
{
    Vector<string> arr = it; // Error

Assuming your Map is a std::map, the elements of a map are pairs of (key,value), so the value is the second element of the pair:

Vector<string> arr = it->second;
