C++ STL List的基本操作

#include<iostream>
#include<list>
using namespace std;
void display_list(list<int> &l)
{
	list<int>::iterator it;
	for(it=l.begin();it!=l.end();it++) cout<<*it<<" ";
	cout<<endl;
}
void demo_test1()
{
	list<int> l1;
	list<int> l2(10);
	list<int> l3(5,20);
	list<int> l4(l3.begin(),l3.end());
	list<int> l5(l4);
	cout<<"***********************************"<<endl;
	cout<<"打印LIST结构的结果:"<<endl;
	display_list(l3);
	cout<<"***********************************"<<endl;
}
void demo_test2()
{
	list<int> l1;
	cout<<"***********************************"<<endl;
	cout<<"判断链表是否为空:"<<endl;
	if(l1.empty()) cout<<"该链表为空!"<<endl;
	else cout<<"该链表不为空!"<<endl;
	cout<<"***********************************"<<endl;
}
