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

void printList(const list<int>& L)
{
	for (list<int>::const_iterator it = L.begin(); it != L.end(); it++)
	{
		cout << *it << " ";

	}
	cout << endl;
}
void test01()
{
	list<int>L1; //默认构造
	L1.push_back(10);
	L1.push_back(20);
	L1.push_back(30);
	L1.push_front(40);
	L1.push_front(50);

	cout << "第一个元素：" << L1.front() << endl;
	cout << "最后一个元素：" << L1.back() << endl;

	//验证迭代器是不支持随机访问的
	list<int>::iterator it = L1.begin();
	it++;
	it--;
	//it = it+1;  不支持



}

int main()
{
	test01();
	system("pause");
	return 0;
