Thread: string iterator

I'm reading one tutorial about STL iterators. I've noticed that there is iterator support for strings. For example I can do something lke this:

Code:

#include <iostream>
#include <string>

using namespace std;

int main()
{
    string s("Kivla");
    string::iterator it;
   
   for (it = s.begin(); it != s.end();++it)
   {
       cout<<*it;
   }
}

I wonder what is the benefit of using iterators with strings (there must be some benefit otherwise iterators wouldn't have been defined)?
In which cases they are useful for strings?
