C++/List/list const iterator
Create list iterator

#include <string>
#include <iostream>
using namespace std;
int main()

list<int> list1;
size_t n = 10;
double val = 3.14;

cout << "Size of list1 " << list1.size() << endl;
cout << "Size of list2 " << list2.size() << endl;

// Create list iterator
list<double>::const_iterator i;

}
Loop through list using list<char>::const_iterator
