C++遍历list元素

#include<list>
//define list
list<int> order1;		//record rack number
list<int> order2;		//record position in rack

//After order1.push_back() and order2.push_back() operations

list<int>::iterator iter1,iter2;
			
for (iter1 = order1.begin(); iter1 != order1.end(); iter1++)
{
    
    
	cout << "order1 = "<<*iter1 << endl;			
}
for (iter2 = order2.begin(); iter2 != order2.end(); iter2++)
{
    
    
	cout << "order2 = " << *iter2 << endl;
}
