使用示例：

#include <iostream>
#include <algorithm>
#include <list>
#include <vector>

using namespace std;

void Print(int&
 
 Ele)
{
	cout << Ele << ", ";
}

void main()
{
	list<int> l1;
	vector<int> l2;
	l1.push_back(1);
	l1.push_back(2);
	l1.push_back(3);
	l1.push_back(4);
	l1.push_back(5);
	l2.push_back(1);
	l2.push_back(2);
	l2.push_back(3);
	l2.push_back(5);
	l2.push_back(4);

	cout <<
 
 "l1: " << endl;
	for_each(l1.begin(), l1.end(), Print);
	cout << endl;
	cout << "l2: " << endl;
	for_each(l2.begin(), l2.end(), Print);
	cout << endl;

	bool b = lexicographical_compare(l1.begin(), l1.end(), l2.begin(), l2.end());
	if (b)
	{
		cout <<
 
 "l1 < l2. " << endl;
	}
	else
	{
		cout << "l1 >= l2. " << endl;
	}
