The __c++ of Iteractor in C + +

Iterator is an iterator in the C + + standard library (STL) ~ ~ ~
For example, you build a linked list (remember #include <list>
#include <iostream>)
List<char> A;
Then list<char>::iterator it, so that you can traverse the list of the ~
In fact, you can think of it as something like a pointer ~ Of course, just the use of the same, using the way and declarative way but completely different oh ~ ~


Can explain the usefulness of iterator ~
#include <list>
#include <iostream>
using namespace Std;


void Main (void)
{
int A[]={1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
List<int> name (A,A+10);


List<int>::iterator it; Iterators, similar to pointers, but are written differently and can be used to traverse the members of a list.
for (it = Name.begin (); it!= name.end (); it++)
{
cout << *it << Endl;
}
}
