iterator begin ();
const_iterator begin () const;
Return iterator to beginning
Returns an iterator referring to the first element in the list container.
Parameters
none
Return Value
An iterator to the beginning of the sequence.
Both iterator and const_iterator are member types. In the list class template, these are bidirectional iterators.

// list::begin
#include <iostream>
#include <list>
using namespace std;
int main ()
{
int myints[] = {75,23,65,42,13};
list<int> mylist (myints,myints+5);
list<int>::iterator it;
cout << "mylist contains:";
for ( it=mylist.begin() ; it != mylist.end(); it++ )
cout << " " << *it;
cout << endl;
return 0;
}

Output:
mylist contains: 75 23 65 42 13

Complexity
Constant.
