c++ list_iterator demo

#include <iostream>
#include <list>
using namespace std;

typedef list<int> IntegerList;
int main()
{
    IntegerList    intList;
    for (int i = 1; i <= 10; ++i)
       intList.push_back(i * 2);
    for (IntegerList::const_iterator ci = intList.begin(); ci != intList.end(); ++ci)
       cout << *ci << " " << endl;
    return 0;
}
