STL list 的循环

#include <iostream>
#include <list>
int main()
{
// 方法一：
list<int> Day = {1,2,3,4,5,6};
auto &point = Day.front();
for (auto &point :Day)
{
cout << "lalalaland" << endl;

}

//方法二：
cout << "---------------------" << endl;
list<int> ::iterator it;
for ( it = Day.begin(); it!=Day.end(); it++)
{

cout << "lalaland2" << endl;

}
// 方法三：
cout << "-------------------" << endl;

for each (auto &point in Day)
{
cout << "lalaland3" << endl;
}

using namespace std;

getchar();
return 0;

}
